Question 697182
High this is only a review but I want to remember how to get the answer. The question is:{{{sqrt(625x^4y^3z) divided by sqrt(90xyz)}}}


{{{sqrt(625x^4y^3z)/sqrt(90xyz)}}} ------- {{{sqrt((625x^4y^3z)/90xyz)}}}------- {{{sqrt((5^2(5)(5)x^2(x)(x)y^2(y)z)/3^2(2)(5)xyz))}}} ----- {{{sqrt((5^2(5)cross((5))x^2(x)cross(x)y^2cross(y)cross(z))/3^2(2)cross((5))cross(xyz)))}}} 


{{{sqrt((5^2(5)x^2 * xy^2)/(3^2(2)))}}} ------  {{{(5xy/3) * (sqrt(5x)/sqrt(2))}}} 


{{{(5xy/3) * (sqrt(5x) * sqrt(2)/(sqrt(2)*sqrt(2)))}}} ------ Rationalizing denominator


{{{(5xy/3) * (sqrt(10x)/(sqrt(2^2)))}}} ----- {{{(5xy/3(2)) * sqrt(10x)}}} ------ {{{highlight_green((5xy/6) * sqrt(10x))}}}, or {{{highlight_green(5xy * sqrt(10x)/6))}}}


You can do the check!!
