(5⁸-3*5⁶):2i jedna piata
------------------------------=
2*5⁶-5⁵
Licznik =(5⁸-3*5⁶):2i 1/5 = 5⁶ *(5² -3):11/5 = 5⁶*(25 -3) *5/11 = 5⁶*22*5/11= 5⁷*2
Mianownik = 2*5⁶-5⁵= 5⁵*(2*5 -1) = 5⁵*(10 -1) = 5⁵*9
Uamek = Licznik : mianownik = (5⁷*2 ): (5⁵*9 )= 2/9*5²
(2²³-3*2²¹):0,02
--------------------=?
2¹⁵*25
Licznik = (2²³-3*2²¹):0,02 = 2²¹*(2² -3) : 2/100 = 2²¹*(4-3): 1/50 = 2²¹*1*50/1=
= 2²¹*2*25 = 2²² *5²
Mianownik = 2¹⁵*25 = 2¹⁵*5²
Uamek = Licznik : Mianownik = (2²² *5² ): ( 2¹⁵*5²) = 2⁷
