Question

Aplicando a definiçao de potencia com expoente negativo calcule

a)7^4x7^2
b)(8^2)^5
c)10^9:10^6
d)6^2x6x6^4
e)(2^10)^3
f)(5x3)^2
h)-2^5

Answer 1

7^4 . 7^2 = 2401 x 49 = 117.649
(8^2)^5 = 1.073.741.824
10^9 :10^6 = 10^3 = 1000
6^2 . 6 . 6^4 = 279.936
(2^10)^3 = 1.073.741.824
(5x3)^2 =225
-2^5 = -32
