resolva
a- 5⁷.5³
b- 3⁹:3⁵
c- (2⁴)²
d- 7- ²
e- 12². 35²
f- 3³: 3⁴​

Answer 1

Olá, tudo bem?

$a) {5}^{7} \times {5}^{3} = {5}^{7 + 3} = \textcolor{red}{ {5}^{10} } \\ \\ b) {3}^{9} \div {3}^{5} = {3}^{9 - 5} = \textcolor{red}{ {3}^{4} } \\ \\ c)( {2}^{4} {)}^{2} = {2}^{4 \times 2} = \textcolor{red}{ {2}^{8} } \\ \\ d) {7}^{ - 2} = ( \frac{1}{7} {)}^{2} = \frac{1}{7} \times \frac{1}{7} = \textcolor{red}{ \frac{1}{49} } \\ \\ e) {12}^{2} \times {35}^{2} = (12 \times 35 {)}^{2} = \textcolor{red}{ {420}^{2} } \\ \\ f) {3}^{3} \div {3}^{4} = {3}^{3 - 4} = {3}^{ - 1} = (\frac{1}{3} {)}^{1} = \textcolor{red}{ \frac{1}{3} }$

Espero ter ajudado :-) Bons estudos.
