Question 78053
{{{sqrt(72x^3)}}}


{{{sqrt(9*8x^2x)}}} Rewrite 72 as 9*8 and rewrite x^3 as x^2*x


{{{sqrt(9)sqrt(x^2)*sqrt(8x)}}} Break up the square root


{{{3x*sqrt(8x)}}} Reduce


{{{3x*sqrt(4*2x)}}}rewrite 8 as 4*2


{{{3x*sqrt(4)*sqrt(2x))}}} break up the square root


{{{3x*2*sqrt(2x))}}} Reduce

{{{6x*sqrt(2x))}}} Multiply. This is the reduced form.
