Question

помогите!!! пожалуйста!!!

Answer 1

$sqrt{81cdot 25}-frac{sqrt{27}}{sqrt{3}}+2sqrt{left(-4right)^2};$
$2sqrt{left(-4right)^2}-frac{sqrt{27}}{sqrt{3}}+sqrt{81cdot 25}$
$2 sqrt{16}- frac{ sqrt{27} }{ sqrt{3} } + sqrt{25cdot81} ;$
$2cdot4- frac{ sqrt{27} }{ sqrt{3} } + sqrt{25cdot81} ;$
$50.$
