a) = 3/4+1+1/4 = 2
b) = -4/3 : 8/9 = 3/2
c) = 5-16 = -11
d) = 4906 * 32768 / 16777216 = 8
a) 3/4 + 2/3 : (-8/12 + 1/4) = 9/12 + 8/12 : (-8/12 + 3/12) =17/12 : (-5/12) = 17/12 * (-12/5) = - 204/60 = -3,4
b)(-2/3) do potęgi 2 : 8/9 do potęgi -1 = 4/9 : 9/8 = 4/9 * 8/9 = 2
c)√25 - 16 = 5 - 16 = -11
d)4 do pot.6 * 8 do pot.5 : 16 do pot.6 = 2 do pot. 12 * 2 do pot. 15 : 2 do pot 24 = 2 do pot. 27 : 2 do pot.24 = 2 do pot. 3 = 8
Mam nadzieję że zrozumiesz ;)
