Answer 2

1.
a) 5/6 * 3/5 = 15/30 = 1/2
2/9* 6/7 = 12/63
(3/4) do potegi 2 = 9/16
b)4/9 * 1/2 = 4/18 = 2/9
4/5 *1/2= 4/10 = 2/5
(3/7) do potegi 2 = 9/49
c) 1/4 * 3/7 = 3/28
3/5*5/8= 15/40 = 3/8
( 2/3) do potegi 3 = 8/27
2. oblicz
a) 1 4/9 * 12= 13/9 * 12/1 = 156/9 = 52/3
6 *2 1/2= 6/1 * 5/2 = 30/2 = 15
2 3/8*12= 19/8 * 12/1 = 228/8 = 28 1/2
(1 1/4) do potegi 2= 25/16
(1 1/4) do potegi 3= 125/64
b)4 2/7 * 3 1/2= 30/7 * 7/2 = 30/2 = 15
8 1/3 * 2 2/5= 25/3 * 12/5 = 5/1 * 4/1 = 20
4 1/5 * 2 1/7 = 21/5 * 15/7 = 3/1 * 3/1 = 9
(1 2/3) do potegi 3= 125/27
(2 1/2) do potegi 2= 25/4
