cuberoot(64a^6b^2)
cuberoot(64) * cuberoot(a^6) * cuberoot(b^2)
4* (a^6)^1/3 * (b^2)^1/3
4 (a^(6*1/3))(b^(2*1/3))
4a^2 (b^2/3)
4a^2 * cuberoot(b^2)
notice that I went back to cuberoot of b^2 because i could not simplify it more
*******************
sqr(50s^2t^4)
sqr(50) * sqr(s^2) * sqr(t^4)
sqr(25*2) *(s^2)^1/2 * (t^4)^1/2
sqr(25)* sqr(2) * (s^(2*1/2))(t^(4*1/2))
5sqr(2)* (s^2/2)(t^4/2)
5st^2 sqr(2)
*********************
fourthroot(256x^16y^28)
froot(256) * froot(x^16) * froot(y^28)
4 *(x^16)^1/4 (y^28)^1/4
4 * (x^(16*1/4))(y^(28*1/4))
4 (x ^ 16/4)(y^ 28/4)
4x^4y^7
