Choose the correct simplification of x to the 2nd power over y to the 5th power all raised to the 4th power. (5 points)

x to the 8th power over y to the 9th power
y12
x12y8
x to the 8th power over y to the 20th power

Answer 1

`\left( \cfrac{x^2}{y^5}\right)^4 = \cfrac{(x^2)^4}{(y^5)^4} = \cfrac{x^8}{y^(20)}`
