Question 63388
{{{(7*sqrt(7)+4*sqrt(2))(5*sqrt(7)+3*sqrt(2))}}} Multiply the terms in the first bracket by each of the terms in the second bracket in turn.
{{{7*sqrt(7)*5*sqrt(7)+7*sqrt(7)*3*sqrt(2)+4*sqrt(2)*5*sqrt(7)+4*sqrt(2)*3*sqrt(2))}}} 
{{{35*sqrt(7)*sqrt(7)+21*sqrt(7)*sqrt(2)+20*sqrt(2)*sqrt(7)+12*sqrt(2)*sqrt(2))}}} 
{{{35*7+21*sqrt(14)+20*sqrt(14)+12*2)}}} 
{{{245+41*sqrt(14)+24}}} 
{{{269+41*sqrt(14)}}}
