Question 953728
(b), even value for root and exponent; looking for PLUS or MINUS x.


(c), can be a little easier looking as only EXPONENTS:


{{{((729*x^6)^(1/2))^(1/3)}}}, which might not display well when rendered on the site.  Know the Rules for Exponents.


{{{(729^(1/2)*x^(6*(1/2)))^(1/3)}}}


{{{(27*x^3)^(1/3)}}}


{{{27^(1/3)*x^(3*(1/3))}}}


{{{highlight(3*x)}}}
