Question

Oblicz : 1.) ( 1 1/2 - 1 1/3) ^ 2 - (-2)^2 2.) (0,75+ 1 1/3) : (-1/4) + 8 ^(1/3) 3.) (11/2 - 7/3 )^2 - (9/4 ) ^ (1/2)

Answer 1

1) (1 1/2 - 1 1/3) = 1/6 * 2 = 3/6 - (-2) = 5/6 * 2 = (-1 4/6) = (-1 2/3)

2) (0,75 + 1 1/3) = 2 1/12 : (-1/4) = (-8 1/3) + 8 = 1/3 * (-1/3) = (-1/6)

 

Nie wiem, czy dobrze, ale liczą się dobrę chęci!
