Introduction

In mathematics, expressions are used to represent mathematical operations or values. When we are given an expression, we need to evaluate it to find its equivalent value. In this article, we will discuss which expression is equivalent to $14 \times 14$. We will analyze each option and determine which one is correct.

Understanding the Expression $14 \times 14$

The expression $14 \times 14$ represents the product of two numbers, 14 and 14. To evaluate this expression, we need to multiply 14 by itself. This can be done using the multiplication property of equality, which states that if $a = b$, then $a \times c = b \times c$.

Evaluating the Expression

To evaluate the expression $14 \times 14$, we can use the multiplication property of equality. We can multiply 14 by itself to get:

$$14 \times 14 = 14 \times (14 \times 1)$$

Using the associative property of multiplication, we can rewrite this as:

$$14 \times 14 = (14 \times 14) \times 1$$

Now, we can multiply 14 by 14 to get:

$$14 \times 14 = 196$$

Analyzing the Options

Now that we have evaluated the expression $14 \times 14$, we can analyze each option to determine which one is equivalent.

Option A: $2^2$

Option A is $2^2$, which represents the exponentiation of 2 to the power of 2. To evaluate this expression, we need to raise 2 to the power of 2. This can be done using the exponentiation property of equality, which states that if $a = b$, then $a^c = b^c$.

$$2^2 = 2 \times 2 = 4$$

This option is not equivalent to $14 \times 14$.

Option B: $2^{14}$

Option B is $2^{14}$, which represents the exponentiation of 2 to the power of 14. To evaluate this expression, we need to raise 2 to the power of 14. This can be done using the exponentiation property of equality.

$$2^{14} = 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 = 16384$$

This option is not equivalent to $14 \times 14$.

Option C: $14^2$

Option C is $14^2$, which represents the exponentiation of 14 to the power of 2. To evaluate this expression, we need to raise 14 to the power of 2. This can be done using the exponentiation property of equality.

$$14^2 = 14 \times 14 = 196$$

This option is equivalent to $14 \times 14$.

Option D: $14^{34}$

Option D is $14^{34}$, which represents the exponentiation of 14 to the power of 34. To evaluate this expression, we need to raise 14 to the power of 34. This can be done using the exponentiation property of equality.

14^{34} = 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \times 14 \<br/> # Frequently Asked Questions (FAQs) About Equivalent Expressions
