Question 794069
Can someone please help me solve this?

Simplify the expression.
{{{(4sqrt(5)+sqrt(3))(2sqrt(2)-sqrt(7))}}}
---------------
There's nothing to solve.  It's just multiplication.
{{{(4sqrt(5)+sqrt(3))(2sqrt(2)-sqrt(7))}}}
= {{{(4sqrt(5))*(2sqrt(2)-sqrt(7)) + sqrt(3)*(2sqrt(2) - sqrt(7))}}}
= {{{8sqrt(10) - 4sqrt(7) + 2sqrt(6) - sqrt(21)}}}
------------
Is that simpler?  Not by much, imo.
It was 4 terms, now it's 4 terms.
