Question

a) 12 · [√9 + (√144 − 2^4)]
b) √81 + [(−3)^3 + √36]^2

Answer 1

Resposta:

a) $-12$

b) $450$

Explicação passo a passo:

a) $12\left(\sqrt{9}+\left(\sqrt{144}-2^4\right)\right)\\=12\left(\sqrt{9}+\sqrt{144}-2^4\right)\\=12\left(-1\right)\\=-12$

b) $\sqrt{81}+\left(\left(-3\right)^3+\sqrt{36}\right)^2\\=9+441\\=450$
