Can someone help me convert this radical expression to exponential form?

Question

√64x¹²y²⁰

Answer 1

√64x¹²y^{20 =}

sqrt(8^2* x^12 * y^20)

= sqrt(8^2) * sqrt(x^12) * sqrt(y^20)

sqrt multiplies each power by 1/2:

= 8^(2*1/2) * x^(12*1/2) * y^(20*1/2)

= 8 * x6 * y10

Answer 2

square root of 64 = 8

square root of a power is half the power

sqrx^12 = x^6

sqry^20 = y^10

answer is

8x⁶y¹⁰
