Question

CALCULE AS POTENCIA DOS RACIONAIS:

A) (1/3 ) 4

b) (1 2/4 ) 2

C) (2,5) 2

D) (2,5) 3

e) (3/5) 0

F) 3/7) 2

g) (1/10) 3

Answer 1

( 1/3)⁴  = 1/3 * 1/3 * 1/3 * 1/3 =  1/81
(12/4)² = 3²  = 3 * 3 = 8
( dividi 12 por 4 )

(2.5)² = ( 25/10) = 5/2 ou ( 5/2)² = 5/2 * 5/2 = 25/4 ***
(2.5)³  =  idem acima   (5/2 )³  = 5/2 * 5/2 * 5/2 =125/8 ****
(3/5)⁰ =   1 ***  ( todo número elevado á potencia zero = 1 )
( 3/7)² = 3/7 * 3/7 = 9/49 ***
( 7/10)³ = 7/10  * 7/10 * 7/10 = 343/1000 ***
