Question 983566
Hello :) 
Can Anyone teach me what to do in this question?
Thanks in advance :)
3a sqrt(3b) + a sqrt(5b) +a sqrt(3b) — 4b sqrt(5b)
Anyone can explain how :)
Thank you! 
<pre>{{{3a * sqrt(3b) + a * sqrt(5b) + a * sqrt(3b) - 4b * sqrt(5b)}}}
{{{highlight_green(4a*sqrt(3b) + a * sqrt(5b) - 4b * sqrt(5b))}}}, or {{{highlight_green(4a*sqrt(3b) + sqrt(5b)(a - 4b))}}}
