Verified answer

Resposta:

a) 4^3*4^-2 = 4^(3-2) = 4^1 = 4

b) 6^3*6^-7 = 6^(3-7) = 6^-4 = 1/6^4 = 1/1296

c) 7^-10*7^-5 = 7^(-10-5) = 7^(-15)

d) 9^5/9^3 = 9^(5-3) = 9^2 = 81

e) 3^-6÷3^-8 = 3^(-6+8) = 3^2 = 9

f) 4^16÷4^-4 = 4^(16+4) = 4^20

g) 10^6÷10^-12 = 10^(6+12) = 10^18

h) 7^-6÷7^-8 = 7^(-6+8) = 7^2 = 49
