Question

(1/2)^5 x 4^5 =
(3/5)^4 : (1/5)^4 =
(-1/3)^3 : (1/9)^3 =
(4/3)^3 x (3/4)^3 =
(-0,2)^9 : 0,1^9 =
0,2^3 x 10^3 =

Answer 1

(1/2)^5 x 4^5=2^-5 x (2^2)^5=2^-5 x 2^10=2^5
(3/5)^4 : (1/5)^4 =(3/5 : 1/5)^4=(3/5 x 5)^4=3^4
(-1/3)^3 : (1/9)^3 =(-1/3 : 1/9)^3=(-1/3 x 9)^3=(-3)^3
(4/3)^3 x (3/4)^3 = (4/3 x 3/4)^3=1^3=1
(-0,2)^9 : 0,1^9 =(-2/10 : 1/10)^9=(-2/10 x 10)^9=(-2)^9
0,2^3 x 10^3 =(2/10 x 10)^3=2^3
