Question 77555
If you want to reduce {{{sqrt(40x)}}} then


{{{sqrt(4*10x)}}} rewrite 40 as the product of 4 and 10


{{{sqrt(4)*sqrt(10x))}}} Rewrite the square root of the product as the product of square roots (ie {{{sqrt(x*y)=sqrt(x)sqrt(y)}}}


{{{2*sqrt(10x))}}} since 4 is a perfect square, it reduces to 2. So this is your reduced form.
