Which Expression Is Not Equivalent To A ⋅ C ⋅ 5 ⋅ 5 A \cdot C \cdot 5 \cdot 5 A ⋅ C ⋅ 5 ⋅ 5 ?A. 25ac B. 10ac C. 25ca

Introduction

In mathematics, expressions are often simplified or rewritten to make them easier to understand or work with. However, it's essential to ensure that the simplified expression is equivalent to the original one. In this article, we will explore which expression is not equivalent to $a \cdot c \cdot 5 \cdot 5$.

Understanding the Original Expression

The original expression is $a \cdot c \cdot 5 \cdot 5$. This expression involves the multiplication of four numbers: two variables, $a$ and $c$, and two constants, $5$ and $5$. To simplify this expression, we can use the associative property of multiplication, which states that the order in which we multiply numbers does not change the result.

Simplifying the Original Expression

Using the associative property, we can rewrite the original expression as $(a \cdot c) \cdot (5 \cdot 5)$. This simplification is valid because the order of multiplication does not affect the result. We can further simplify the expression by multiplying the constants, $5$ and $5$, which gives us $(a \cdot c) \cdot 25$.

Examining the Options

Now, let's examine the three options provided:

A. 25ac: This option suggests that the expression is equivalent to $25ac$. To determine if this is true, we can compare it to the simplified original expression, $(a \cdot c) \cdot 25$. Since $25ac$ is equivalent to $(a \cdot c) \cdot 25$, this option is indeed equivalent to the original expression.

B. 10ac: This option suggests that the expression is equivalent to $10ac$. However, we know that the original expression involves the multiplication of $5$ and $5$, which results in $25$. Therefore, the expression $10ac$ is not equivalent to the original expression.

C. 25ca: This option suggests that the expression is equivalent to $25ca$. Similar to option A, we can compare this to the simplified original expression, $(a \cdot c) \cdot 25$. Since $25ca$ is equivalent to $(a \cdot c) \cdot 25$, this option is indeed equivalent to the original expression.

Conclusion

In conclusion, the expression that is not equivalent to $a \cdot c \cdot 5 \cdot 5$ is 10ac. This is because the original expression involves the multiplication of $5$ and $5$, resulting in $25$, whereas the expression $10ac$ does not involve the multiplication of $5$ and $5$. Therefore, $10ac$ is not equivalent to the original expression.

Introduction

In our previous article, we explored which expression is not equivalent to $a \cdot c \cdot 5 \cdot 5$. We simplified the original expression using the associative property of multiplication and examined the three options provided. In this article, we will answer some frequently asked questions related to the topic.

Q&A

Q: What is the associative property of multiplication?

A: The associative property of multiplication states that the order in which we multiply numbers does not change the result. This means that we can regroup the numbers in a multiplication problem without changing the result.

Q: How can we simplify the original expression?

A: We can simplify the original expression by using the associative property of multiplication and multiplying the constants, $5$ and $5$. This gives us $(a \cdot c) \cdot 25$.

Q: Why is option B not equivalent to the original expression?

A: Option B is not equivalent to the original expression because it does not involve the multiplication of $5$ and $5$, resulting in $25$. The original expression involves the multiplication of $5$ and $5$, which is a key part of the expression.

Q: Can we simplify the expression further?

A: Yes, we can simplify the expression further by multiplying the variables, $a$ and $c$. However, this would not change the fact that option B is not equivalent to the original expression.

Q: What is the difference between the original expression and option B?

A: The original expression involves the multiplication of $5$ and $5$, resulting in $25$. Option B does not involve the multiplication of $5$ and $5$, resulting in a different value.

Q: Can we use the commutative property of multiplication to simplify the expression?

A: Yes, we can use the commutative property of multiplication to simplify the expression. However, this would not change the fact that option B is not equivalent to the original expression.

Q: What is the commutative property of multiplication?

A: The commutative property of multiplication states that the order in which we multiply numbers does not change the result. This means that we can swap the numbers in a multiplication problem without changing the result.

Q: Can we use the distributive property of multiplication to simplify the expression?

A: Yes, we can use the distributive property of multiplication to simplify the expression. However, this would not change the fact that option B is not equivalent to the original expression.

Q: What is the distributive property of multiplication?

A: The distributive property of multiplication states that we can multiply a single number by each of the numbers in a group without changing the result.
