how do you write radicals as powers? please help me with the following question, I know the answer but I don't know HOW to get it. I must learn this so please help me.
y5/3 is under the square root sign
sorry I retyped this, but I made a mistake typing it before

roots are fractional powers. The nth root of x is x^(1/n)
Because if y is the nth root of x, y^n = x.
(x^(1/n))^n = x^(n/n) = x^1 = x
√(y^{5/3} = (y^{5/3})^{1/2} = y^{5/6}
