Question

Calcule
a) (-4/3)^3
B) (+1/3)^4
c) (-5)^-3
d) (+10) -4
e) (-7^8) -2
f) (5^9) 0​

Answer 1

Resposta:

a) (-4/3)^3 = -64/27

b) (1/3)^4 = 1/81

c) (-5)^-3 = 1/-5^3 = -1/125

d) (10) -4 = 6 ou se for (10)^-4 = 1/10^4 = 1/10,000

e) (-7^8) -2 = -5764801-2 = -5764803 ou se for

(-7^8)^-2 = 7^-16 = 1/7^16

f) (5^9) 0 = 1,953,125 ou se for (5^9)^0 = 1
