Best ResponseYou've already chosen the best response.0You should use \[\sqrt{x} = x^{\frac{1}{2}}\]

Best ResponseYou've already chosen the best response.0use power rules, and \[\frac{x}{y} = x\cdot y^{1}\]

Best ResponseYou've already chosen the best response.0You do have the same bases there, so all you need no know then is what \[x^a \cdot x^b\] is

Best ResponseYou've already chosen the best response.0oh, so it will be like \[3^{3(1/5)}\] right?

Best ResponseYou've already chosen the best response.0nearly, but: \[\left( x^a \right) ^b = x^{a\cdot b} \]

Best ResponseYou've already chosen the best response.0\[\sqrt{3^{5}} = 3^{1/5} . so you get 3^{3}/ \]

Best ResponseYou've already chosen the best response.0hence that will be \[3^{31/5}\]

Best ResponseYou've already chosen the best response.0that is exactly the mistake! \[ \sqrt{3^5} = \left( 3^5 \right)^{\frac{1}{2}}\]

Best ResponseYou've already chosen the best response.0oh no i think i get it wrong. that should be 3^5/2

Best ResponseYou've already chosen the best response.0And just for completeness, \[x^{\frac{1}{5}} = \sqrt[5]{x} \]

Best ResponseYou've already chosen the best response.0First , You 3^5=3*3^4, so SQRT(3^5)=SQRT(3)*3^2,===>(3^3)/(SQRT(3)*3^2)=3/SQRT(3)=SQRT(3) It may be TRUE
