prosze was! rróbcie z obliczeniami te przyklady: /- to jest jako kreska ułamkowa!! *-razy

6*2 i 1/2= 6 * 5/2 = 15
2 i 3/8 *12= 19/8 * 12/1 = 57/2 = 18 i 1/2
(1 i 1/4)do potęgi 3= (5/4)³ = 125/64 = 1 i 61/64
4 i 2/7*3 i 1/2= 30/7 * 7/2 = 15
8 i 1/3*2 i 2/5= 25/8 * 12/5 = 15/2 = 7 i 1/2
4 i 1/5*2 i 1/7= 21/5 * 15/7 = 9
(1 i 2/3) do potęgi 3= (5/3)³ = 125/27 = 4 i 17/27
(2 i 1/2) do potęgi 2 = (5/2)² = 25/4 = 6 i 1/4
6 x 2 1/2 = 6/1 x 5/2 = 15/1 = 15
2 3/8 x 12 = 19/8 x 12/1 = 57/2 = 28 1/2
(1 1/4) DPT3 = 5/4 x 5/4 x 5/4 = 25/16 x 5/4 = 125/64 = 1 61/64
4 2/7 x 3 1/2 = 30/7 x 7/2 = 15/1 = 15
8 1/3 x 2 2/5 = 25/3 x 12/5 = 20/1 = 20
4 1/5 x 2 1/7 = 21/5 x 15/7 = 9/1 = 9
(1 2/3) DPT3 = 5/3 x 5/3 x 5/3 = 25/9 x 5/3 = 125/27 = 4 17/27
(2 1/2) DPT2 = 5/2 x 5/2 = 25/4 = 6 1/4
Mam nadzieję, że pomogłam. :)
