Question

(-√4)(-2)2+(-1)5(√16)

Answer 1

Hola.

$\mathsf{\left(-\sqrt{4}\right)\left(-2\right)2+\left(-1\right)5\left(\sqrt{16}\right)=}\\\\ \mathsf{\left(-\sqrt{2^2}\right)(-4)-5\left(\sqrt{2^4}\right)=}\\\\ \mathsf{\left(-2\right)(-4)-5\left(2^2\right)=}\\\\ \mathsf{8-5\left(4\right)=}\\\\ \mathsf{8-20=}\\\\ \boxed{\mathsf{-12}}$

Buenos estudios.
