If a/4 = 9/a, then

a. a2=36
b. 4a = 9a
c. a + 4 = 9 + a
d. a - 4 = 9 - a

Option a.

Step-by-step explanation:

It is important to remember the "Product of powers property", which states that:

Then, given the expression , you need to apply the Multiplication property of equality, which states that:

Therefore:

- Multiply both sides of the equation by "a":

- Multiply both sides of the equation by "4". Then you get:

This matches with the option a.
