Question 695899
A.  Rationalize by multiplying by 1 in the form of {{{sqrt(5)/sqrt(5)}}}
{{{(10/sqrt(5))(sqrt(5)/sqrt(5)) = (10sqrt(5))/(sqrt(5)sqrt(5)) = (10sqrt(5))/sqrt(25) = (10sqrt(5))/5 = (2cross(10)sqrt(5))/(1cross(5)) = highlight_green(2sqrt(5))}}}

B.  Rationalize by multiplying by 1 in the form of {{{sqrt(x)/sqrt(x)}}}
{{{sqrt(w^4/x^3) = (sqrt(w^4)/sqrt(x^3))(sqrt(x)/sqrt(x)) = (sqrt(w^4)sqrt(x))/(sqrt(x^3)sqrt(x)) = sqrt(x*w^4)/sqrt(x^4) = sqrt(x*w^2*w^2)/sqrt(x^2*x^2) = highlight_green((w^2sqrt(x))/x^2)}}}
