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
√(y5/3 = (y5/3)1/2 = y5/6
