Question

calculeaza puterile de exponent 1 , 2 , 3 si 4 pentru fiecare dintre numerele : ½ , -¼ , 0,2 , 0,(3) , -0,002​

Answer 1

Răspuns:

(1/2)^1 = 1/2

(1/2)^2 = 1/4

(1/2)^3 = 1/8

(1/2)^4 = 1/16

(-1/4)^1 = -1/4

(-1/4)^2 = 1/16

(-1/4)^3 = -1/64

(-1/4)^1 = 1/256

0,2 = 1/5

(1/5)^1 = 1/5

(1/5)^2 = 1/25

(1/5)^3 = 1/125

(1/5)^4 = 1/625

0,(3) = 1/3

(1/3)^1 = 1/3

(1/3)^2 = 1/9

(1/3)^3 = 1/27

(1/3)^4 = 1/81

-0.002 = -2/1000 = -1/500

(-1/500)^1 = -1/500 ( -0.002 )

(-1/500)^2 = 1/500^2 = 0.000004

(-1/500)^3 = -1/500^3 = -1/125000000  

(-1/500)^4 = 1/500^4 = 1/62500000000
