Answer 1

(F )

$2 {}^{7} .2 {}^{2} = 2 {}^{9}$

( V )

$(7 {}^{3} ) {}^{2} = 7 {}^{3 + 2} = 6$

Answer 2

Resposta:

Olá bom dia!

(F) $2^7.2^2 = 2^{7+2} = 2^9$

(V) $(7^3)^2 = 7^{3.2} = 7^6$

(F) $2^{3^2} = 2^9 \neq (2^3)^2=2^{3*2}=2^6$

(F) (5-2)² = 3² = 9 ≠ 5² - 2² = 25 - 4 = 21

(F) $10^3 / 10^5 = 10^{3-5} = 10^{-2} \neq 10^{15}$
