Don't understand the second one

Last one

(8x^7y^4)^(2/3)  =

8^(2/3) *(x^7)^(2/3) * (y^4)^(2/3)

[8^(1/3)[^2  * [x^14/3]  * [y^8/3]

2^2  *  x^4 * x^(2/3)  *  y^2 * y^(2/3)

4x^4y^2 ∛ [ x^2 y^2 ]   May 27, 2019

(8)5/2=   ( 2*2*2)^5/2 =   (4*2)^5/2 =   2^5  * 2^5/2 = 32 (2*2*2*2*2)^1/2 = 32 * 4 sqrt2 = 128 sqrt 2
