Step-by-step explanation:
Say you have these 2 fractions
Cross multiply as following;
If in the end, both numerator and denominator are equal, then the fractions are equivalent.
Examples:
Example 1
Cross multiply
They're equivalent.
Example 2
Cross multiply
They're not equivalent.
We have been given an expression . We are asked to choose the expressions, which are equivalent to our given expression.
Using exponent property , we can rewrite our given expression as:
Upon looking at our given choices, we can see that option D is the correct choice.
Let us simplify our given expression.
Upon cancelling out from numerator and denominator, we will get:
Using exponent property , we will get:
Therefore, option B is a correct choice as well.
