Question

Oblicz:

2 ^ -2

0,5^ -4

(1 i 1/3) ^-2

Przedstaw w postaci potęgi G i oblicz

4 ^-2 * 4 ^ 3

(-5)^ - 7 : (-5)^ - 9

7 ^-10 : ( 1/7 ^-10

1/6 ^-2 : 5/12 ^-2

(-7 ^-1)^2

^ - do potęgi

/ krseka ułamkowa

Answer 1

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

0,5^-4 = 2^4 = 16

1i1/3^-2 = (4/3)^-2= (3/4)^2 = 9/16

 

4^-2 * 4^3 = (1/4)^2 * 48= 1/16 * 48 = 3

(-5)^-7 : (-5)^-9 = (-1/5)^7 : (-1/5)^9 = (-1/5)^-2 = -5^2

 

reszty nie wiem : D
