Question 567517
2• radicand of 48y^5 power - 3y•radicand of 12y^3 power
Assume the problem is:
;
{{{2*sqrt(48y^5) - 3y*sqrt(12y^3)}}}
Factor inside the radicals to reveal some perfect squares
{{{2*sqrt(16*3*y^2*y^2*y) - 3y*sqrt(4*3*y^2*y)}}}
Extract the square root of those squares
{{{4*y*y*2*sqrt(3y) - 2*y*3y*sqrt(3y)}}}
which are now like terms
{{{8y^2*sqrt(3y) - 6y^2*sqrt(3y)}}} = {{{2y^2*sqrt(3y)}}}
