Answer:
The Correct answer is...
y^18
(y^2)^5 So you're going to do 2 multiplied by 5.
2 x 5 = 10
Now that you have y^10 you're gonna multiply is by y ^8 but because the numbers are exponents we're going to add them together.
10 + 8 = 18
So the answer that you will get is... Y^18
Have a good day :)
