Question 984651
{{{4w*sqrt(54u^3)+u*sqrt(96uw^2)}}}
Factor inside the radicals to reveal perfect squares
{{{4w*sqrt(9*6*u^2*u)+u*sqrt(16*6*u*w^2)}}}
Extract the square root of those perfect squares
{{{3*u*4w*sqrt(6u)+4*w*u*sqrt(6u)}}}
{{{12*u*w*sqrt(6u)+4*u*w*sqrt(6u)}}}
like terms so we have
{{{16*u*w*sqrt(6u)}}}
