√125+2√27-√20+3√12 ajudem por favor??

Answer 1

$\sqrt{125}+2 \sqrt{27}- \sqrt{20}+3 \sqrt{12}$
$\sqrt{5*5^{2} }+2 \sqrt{3*3^{2} }- \sqrt{5*2^{2} }+3 \sqrt{3*2^{2} }$
$5 \sqrt{5}+2*3 \sqrt{3} -2 \sqrt{5} +3*2 \sqrt{3}$
$5 \sqrt{5}+6 \sqrt{3} -2 \sqrt{5} +6 \sqrt{3}$
$(5-2) \sqrt{5}+(6+6) \sqrt{3}$
$3 \sqrt{5} +12 \sqrt{3}$
