could someone help me with math?

Question

Use the expanded distributive property of exponents to simplify this expression, write the answer with positive exponents only.

 

(4/a)^2

Answer 1

Exponentiation is just repeated multiplication. Here, you will be multiplying fractions. x² = x * x

 

(4/a)² = (4/a) * (4/a) = 16/a²
