Answer:
6. one
7. 4x²/y²
Step-by-step explanation:
6. Any nonzero real number raised to the power of zero is one, this means anything that looks like a 0 a^0 a0 will always equal 1 if a is not equal to zero.
7. given: (2x/y)²
Solution:
(2x/y)(2x/y)
= 4x²+2xy+2xy/y²
= 4x²/y²
hope it helps, but try to do some research for further clarification regarding with the solution. thank you
