a) (1 3/4)^6 x (2/7)^6=(7/4)^6 x (2/7)^6=(7/4*2/7)^6=(1/2)^6=1/64
b) (0,8)^4 : ( 2 2/3)^4=(8/10)^4:(8/3)^4=(4/5)^4:(8/3)^4=(4/5 x 3/8)^4=(3/10)^4=81/10000
c) (-6,5)^3/(-0,13)^3= (-65/10)^3/(-13/100)^3=(-13/2)^3 x (-100/13)^3=(13/2 * 100/13)^3=50^3=125000
d) (4 1/2)^4 x ( - 2/3)^3 x (-2)^3= (9/2)^4 x (2/3 x 2)^3=81/4 x 81/4 x (4/3)^3= 81/4 x 81/4 x 16/9 x 4/3=972
e) (2 1/2)^4 x 0,6^4 x (-1/15)^4= (5/2)^4 x (6/10)^4 x (-1/15)^4=(-5/2 x 6/10 x 1/15)^4=(-1/10)^4=1/10000
f) 0,3^4 x (2 2/3)^4 / (-4)^4= (3/10)^4 x (8/3)^4 x (-1/4)^4=(-3/10 x 8/3 x 1/4)^4=(-2/10)^4=16/10000==1/625
Myslę, że pomogłam. Liczę na NAj.
