Which of the Following is Equivalent to the Given Expression?

Understanding the Expression

When it comes to algebraic expressions, it's essential to understand the rules of exponents and how to simplify them. In this case, we're given the expression $3yx^2$ and asked to find an equivalent expression from the given options.

The Rules of Exponents

Before we dive into the options, let's quickly review the rules of exponents. When we have a variable raised to a power, we can multiply the variable by itself as many times as the exponent indicates. For example, $x^2$ means $x \cdot x$, and $x^3$ means $x \cdot x \cdot x$. When we have a coefficient (a number) multiplied by a variable raised to a power, we can multiply the coefficient by the variable as many times as the exponent indicates.

Option A: $3 \cdot 3 \cdot y \cdot y \cdot x \cdot x$

Let's analyze Option A: $3 \cdot 3 \cdot y \cdot y \cdot x \cdot x$. This expression is equivalent to $3^2 \cdot y^2 \cdot x^2$, which is not the same as the original expression $3yx^2$. The exponent of 2 is applied to both the coefficient 3 and the variable y, resulting in a different expression.

Option B: $3 \cdot 3 \cdot y \cdot x \cdot x$

Now, let's look at Option B: $3 \cdot 3 \cdot y \cdot x \cdot x$. This expression is equivalent to $3^2 \cdot y \cdot x^2$, which is still not the same as the original expression $3yx^2$. The exponent of 2 is applied to the coefficient 3, but not to the variable y.

Option C: $3 \cdot y \cdot y \cdot x \cdot x$

Finally, let's examine Option C: $3 \cdot y \cdot y \cdot x \cdot x$. This expression is equivalent to $3 \cdot y^2 \cdot x^2$, which is not the same as the original expression $3yx^2$. The exponent of 2 is applied to the variable y, but not to the coefficient 3.

The Correct Answer

After analyzing all the options, we can see that none of them are equivalent to the original expression $3yx^2$. However, if we simplify the expression $3yx^2$ using the rules of exponents, we get $3 \cdot y \cdot x \cdot x$, which is equivalent to $3 \cdot y \cdot x^2$. This is not an option, but it shows that the original expression can be simplified in a way that is not listed.

Conclusion

In conclusion, none of the options are equivalent to the given expression $3yx^2$. However, we can simplify the expression using the rules of exponents to get $3 \cdot y \cdot x^2$, which is not an option. This exercise highlights the importance of understanding the rules of exponents and how to simplify algebraic expressions.

Q&A: Understanding Exponents and Simplifying Algebraic Expressions

Q: What are exponents and how are they used in algebra?

A: Exponents are a shorthand way of writing repeated multiplication. For example, $x^2$ means $x \cdot x$, and $x^3$ means $x \cdot x \cdot x$. Exponents are used to simplify algebraic expressions and are a fundamental concept in mathematics.

Q: How do I simplify an algebraic expression using exponents?

A: To simplify an algebraic expression using exponents, you need to apply the rules of exponents. For example, if you have the expression $3yx^2$, you can simplify it by multiplying the coefficient 3 by the variable y and then multiplying the result by the variable x raised to the power of 2.

Q: What is the difference between a coefficient and a variable?

A: A coefficient is a number that is multiplied by a variable. For example, in the expression $3yx^2$, the coefficient is 3. A variable is a letter or symbol that represents a value. In the expression $3yx^2$, the variables are y and x.

Q: How do I apply the rules of exponents to simplify an expression?

A: To apply the rules of exponents, you need to follow these steps:

1. Identify the variables and their exponents.
2. Multiply the coefficients by the variables as many times as the exponent indicates.
3. Simplify the expression by combining like terms.

Q: What is the rule for multiplying exponents?

A: The rule for multiplying exponents is that when you multiply two variables with the same base, you add their exponents. For example, $x^2 \cdot x^3 = x^{2+3} = x^5$.

Q: What is the rule for dividing exponents?

A: The rule for dividing exponents is that when you divide two variables with the same base, you subtract their exponents. For example, $x^5 \div x^2 = x^{5-2} = x^3$.

Q: How do I simplify an expression with negative exponents?

A: To simplify an expression with negative exponents, you need to apply the rule that $a^{-n} = \frac{1}{a^n}$. For example, $x^{-2} = \frac{1}{x^2}$.

Q: What is the difference between a positive exponent and a negative exponent?

A: A positive exponent indicates that the variable is being multiplied by itself as many times as the exponent indicates. A negative exponent indicates that the variable is being divided by itself as many times as the absolute value of the exponent indicates.

Q: How do I simplify an expression with fractional exponents?

A: To simplify an expression with fractional exponents, you need to apply the rule that $a^{\frac{m}{n}} = \sqrt[n]{a^m}$. For example, $x^{\frac{1}{2}} = \sqrt{x}$.

Q: What is the rule for raising a power to a power?

A: The rule for raising a power to a power is that when you raise a power to another power, you multiply the exponents. For example, $(x^2)^3 = x^{2 \cdot 3} = x^6$.

Q: How do I simplify an expression with multiple exponents?

A: To simplify an expression with multiple exponents, you need to apply the rules of exponents and simplify the expression by combining like terms.

Conclusion

In conclusion, understanding exponents and simplifying algebraic expressions is a fundamental concept in mathematics. By applying the rules of exponents and simplifying expressions, you can solve complex problems and make sense of the world around you.
