Question 917085
how would you solve the sqrt of 8 plus the sqrt of 18? 
:
{{{sqrt(8)}}} + {{{sqrt(18)}}}
Factor inside the radicals to reveal a perfect square
{{{sqrt(4*2)}}} + {{{sqrt(9*2)}}}
extract the square root of those squares = then we have like terms we can add
{{{2sqrt(2)}}} + {{{3sqrt(2)}}} = {{{5sqrt(2)}}}
