Szczegółowe wyjaśnienie:
Uwaga! - ,minus "-" do potęgi parzystej = plus "+"
a) (4/5)²= 4/5 * 4/5 = 16/25
b) -(1,5)² = -15/10 * 15/10 = - 225/100 = -2,25
c) (-3/2)^4 = (3/2)^4 = 81/16 = 5 1/16
d) (-2,2)² = 22/10 * 22/10 = 484/100 = 4,84
e) (1 2/5)² = (7/5)² = 49/25 = 1 24/25
f) - (-2/3)³ = 8/27
g) (-2 2/3)³ = (-8/3)³ = - 512/27 = - 18 26/27
