Accepted Answer

Vamos calcular cada um dos itens:

a) $9^2 = 81$

b) $18^0 = 1$

c) $(-1)^3 = -1$

d) $(-1)^2 = 1$

e) $(-8)^3 = -512$

f) $\left(-\frac{3}{2}\right)^2 = \frac{9}{4}$

g) $\left(-\frac{3}{4}\right)^3 = -\frac{27}{64}$

h) $100^1 = 100$

i) $(6)^{-1} = \frac{1}{6}$

j) $15^{-2} = \frac{1}{225}$
