Question 83606
{{{-3*sqrt(180h^4)}}} Start with the given expression
{{{-3*sqrt(36*5*h^2*h^2)}}} Factor 180 into 36*5 and {{{h^4}}} into {{{h^2*h^2}}}
{{{-3*sqrt(36)*sqrt(5)*sqrt(h^2)*sqrt(h^2)}}} Break up the square roots using the identity {{{sqrt(x*y)=sqrt(x)*sqrt(y)}}}
{{{-3*6*sqrt(5)*h*h}}} Take the square root of any perfect square
{{{-18h^2*sqrt(5)}}} Multiply. So this is the simplified result
