I assume this is :

 

 (x * √ (3a) *  3√b^2)3

 

Writing these in exponential form is easier, Manuel.....then we can just apply the rule that (a^m)^n  = a^(m * n)

 

So we have

 

[ x * ( 3a)^(1/2) * b^(2/3) ]  ^3  =

 

x^3  *  (3a)^(3/2) * b^2  =

 

x^3 * 3a √ [3a ] * b^2

 

 

cool cool cool
