    when you transform a root of something to an exponent it will go under 1/?

    yes when an exponent is a fraction, the top is power, the bottom is a root 16^(1/5) * 2^(1/5) is it possible that 16 is a power of 2?

    Like \[\sqrt{2} = \] 2^1/2

    2^4 yes now, lets use this: when an exponent is a fraction the top is a power the bottom is a root 16^(1/5) ... but 16 = 2^4 2^(4/5) now what happens when we multiply like bases?

    ive explained it as basic as i can when an exponent is a fraction ... the TOP is power, the BOTTOM is a root. \[\large \sqrt[5]{16}\] \[\large \sqrt[5]{2^4}\] \[\large {2^{4/5}}\] now all there is to do is multiply to find an area what is: \[2^{4/5}~*~2^{1/5}\]
