What number? 5?
jimthompson5910 (jim_thompson5910):
the whole number \(\large 5\sqrt{3}\)
jimthompson5910 (jim_thompson5910):
you multiply that by EVERY term inside the parenthesis
so you're multiplying \(\large 5\sqrt{3}\) and \(\large 2\sqrt{3}\)
then
you're multiplying \(\large 5\sqrt{3}\) and \(\large 6\sqrt{19}\)

after all this, you add them together (combine like terms if possible, if not, then just leave it alone)

Thank you.
jimthompson5910 (jim_thompson5910):
now you can simplify things a bit, so you're not completely done

jimthompson5910 (jim_thompson5910):
so 10*sqrt(9) = 10*3 = 30
jimthompson5910 (jim_thompson5910):
which means the final answer is
\[\large 30 + 30\sqrt{57}\]
