Prosze o rozwiązanie 4 przykładów.

Answer 1

A)(5 1/3)^(-2) * (0,75)^(-2) = ((16/3) * (3/4)^(-2) = (12/3))^(-2) = 4^(-2) =0.0625
b) (1 2/3)^10 * (1 2/3)^-8 = (5/2)^10 * (5/2)^-8 = (5/2)^10+(-8) = (5/2)^2 =25/4
c) (4^-3)^-2 :4^6 = 4^-3*(-2) : 4^6 = 4^6 :4^6 = (4/4)^6 = 1^6 = 1
d)[(4/3)^-2]^2 : (4/3)^-4 = (4/3)^-2*2 : (4/3)^-4 = (4/3)^-4 : (4/3)^-4 = 4^-4 / 3^-4 = (4/3)-4 tu inaczej nie wyjdzie :/
e)(1 5/7)^-3 * (7/12)^-3 = (12/7)^-3 * (7/12)^-3 = (12/7 * 7/12)^-3 = (84/84)^-3 = 1^-3 = 1
f)2^-7 * (0,5)^-7 = (2*0,5)^-7 = 1^-7 = 1  
g)(2,6)^-4 * (5/13)^-4 = (2 3/5)^-4 * (5/13)^-4 = (13/5)^-4 * (5/13)^-4 =  (13/5 * 5/13)^-4 = (65/65)^-4 = 1^-4 = 1
h)(4,9)^-1 *: (0,7)^-1 = (4,9/0,7)^-1 = 7^-1
i) (0,4)^-2 : (0,1)^-2 = (0,4/0,1)^-2 = 4^-2
