Answer 1

a) (1¾)^6*(2/7)^6 = (1 1/4 * 2/7)^6 = (7/4*2/7)^6 = (1/2)^6 = 1/64

b) (0,8)^4 : (2 2/3)^4 = ( 0,8:2 2/3)^4 = ( 8/10:8/3)^4 = ( 8/10*3/8)^4 = (3/10)^4 = 81/10000

c) (-6,5)^3/(-0,13)^3 = [-6,5:(-0,13)]^3 = [-65/10:(-13/100)] = [-65/10*(-100/13)] = [-5*(-100)] = 500

d) (4 1/2)^3*(-2/3)^3*(-2)^3 = [ 4 1/2* (-2/3)*(-2)]^3 = [ 9/2*(-2/3)*(-2)]^3 = [3*(-1)*(-2)]^3 = 6^3 = 216

e) (2 1/2)^4 * 0,6^4 * (-1/15)^4 = (5/2)^4*(6/10)^4*(-1/15)^4 = [ 5/2*6/10*(-1/15)]^4 = [1/2*(-1/5)]^4 = (-1/10)^4 = 1/10000

f) 0,3^4*(2 2/3)^4/(-4)^4 = (3/10)^4*(8/3)^4/(-4)^4 = (3/10*8/3)^4/(-4)^4 = (4/5)^4/(-4)^4 = [4/5:(-4)]^4 = [4/5*(-1/4)]^4 = [1/5*(-1)]^4 = (-1/5)^4 = 1/625

 

Myślę że pomogłam ;)
