Question

Como ficaria (raiz de 24 - 4)^2

Answer 1

Olá, Isabela.

$(\sqrt{24}-4)^2=(\sqrt{24})^2-2\cdot\sqrt{24}\cdot4+4^2=\\\\ =24-8\sqrt{24}+16=40-8\sqrt{4\cdot6}=40-8\cdot2\sqrt6=\\\\ =\boxed{40-16\sqrt6}$

Answer 2

(√24-4)^2

=(2√6-4)^2

=2√6.2√6+2.(-4).(2√6)+(-4).(-4)

=24-16√6+16

=40-16√6

=4.(10-4√6)
