You should use \[\sqrt{x} = x^{\frac{1}{2}}\]

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

You do have the same bases there, so all you need no know then is what \[x^a \cdot x^b\] is

oh, so it will be like \[3^{3(1/5)}\] right?

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

\[\sqrt{3^{5}} = 3^{1/5} . so you get 3^{3}/ \]
 3 years ago

dindatc Group TitleBest ResponseYou've already chosen the best response.0
you get 3^3 / 3^1/5
 3 years ago

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

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

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

dindatc Group TitleBest ResponseYou've already chosen the best response.0
hence, its \[3^{3}\]

My answer is true SQRT(3)

dindatc Group TitleBest ResponseYou've already chosen the best response.0
its 3^35/2 = 3^1/2

nowhereman Group TitleBest ResponseYou've already chosen the best response.0
And just for completeness, \[x^{\frac{1}{5}} = \sqrt[5]{x} \]
 3 years ago

dindatc Group TitleBest ResponseYou've already chosen the best response.0
the answer is \[\sqrt{3}\] right?

duc, how do you get sqrt3?

I know the answere, but I dont know how to get to the answer

ok, guys, i appreciate you helping me, i just became your fan

Duc Group TitleBest ResponseYou've already chosen the best response.0
First , 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
