cálculos cálculos cálculos​

Answer 1

Explicação passo-a-passo:

A)

$2 {}^{2} \times 2 {}^{7} = 2 {}^{2 + 7} = 2 {}^{9} = 512$

B)

$( \dfrac{1}{3} ) {}^{3} \times ( \dfrac{1}{3} ) {}^{4} = ( \dfrac{1}{3} ) {}^{3 + 4} = ( \dfrac{1}{3} ) {}^{7} = \dfrac{1}{2187}$

C)

$( - 3) {}^{4} \times ( - 3) {}^{7} - 3 {}^{4 + 7} = - 3 {}^{11} = - 177147$

D)

$5 {}^{6} \div {5}^{7} = 5 {}^{6 - 7} = 5 {}^{ - 1} = \dfrac{1}{5}$

E)

$13 {}^{7} \div 13 {}^{6} = 13 {}^{7 - 6} = {13}^{1} = 13$

F)

$( - 2 {}^{3} ) {}^{5} = - 2 {}^{3 \times 5} = - 2 {}^{15} = - 32768$

G)

$6 {}^{5} \div 2 {}^{5} = (6 \div 2) {}^{5} = 3 {}^{5} = 243$
