Question 766981
<pre>

1) {{{6^(3/4) = (6^3)^(1/4) = (216)^(1/4)}}}

It is the 4th root of 216. Using a calculator, you get the answer as {{{highlight(3.83)}}}

I think you may have confused exponentiation (^) with the multiplation (*) operation.

6*3/4 = 4.5, but 6^(3/4) = 3.83.

2) {{{(-125)^(2/3) }}}

= {{{(-125^(1/3))^2}}} ---> take the cube root of -125 and square it
= {{{(-5)^2}}}
={{{highlight(25)}}}

Hope you got it :)
