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.
The tangent line is perpendicular to the radius, so will have slope
.. -1/2.5 = -0.4 . . . . . . corresponding to the 3rd selection
9.983978e+15 that’s what I think based on the info
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.
