OBLICZ: [2/3 · (1 1/2)² - 7/16 · 2²] : (-1/2)² POMOCY POTRZEBUJĘ TO JAK NAJSZYBCIEJ DAJE NAJ! :)
[2/3 · (1 1/2)² - 7/16 · 2²] : (-1/2)²=
[ 2/3 * (3/2)² - 7/16 * 4 ] : 1/4 = [ 2/3 * 9/4 - 7/4 ] * 4 =
[ 3/2 - 7/4 ] * 4 = [ 6/4 - 7/4] * 4 = (-1/4) * 4 = -1
(1/3*9/4-7/16*4):1/4=(2/3-7/4):1/4=(6/4-7/4):1/4=-1/4:1/4=0
