BASTA INVERTER E TORNAR O EXPOENTE POSITIVO
2^-5 = (2/1) = (1/2)^5 = 1/32 ( Modelo)
5^-3 = ( 1/5)³ = 1/125
(1/2)^-2 = (2/1)² = 4
6^-4 = (1/6)^4 = 1/1296
(2/3)^-3 =(3/2)³ = 27/8
4^-6 = ( 1/4)^6 = 1/4096
(5/3)^-2 = ( 3/5)² = 9/25
3^-5 = ( 1/3)^5 = 1/243
( 1/7)^-1 = 7¹ = 7
a)
14^5 = 14² * 14² * 14 = 196 * 196 * 14 =537824
40.5² = 1640,25
7,3³ =389,017
55^4= 9150625
524²= 274576
