a) ∛10000
÷
∛10
b) -2.4-3.6*(1⅜:3.3- ⁵₉)
⁵₉ -> to ułamek pięć dziewiątych
a) ∛10 000 : ∛10 = ∛(1000 * 10) : ∛10 = 10∛10 : ∛10 = 10
b) -2.4 - 3.6*(1⅜:3.3- ⁵₉) = -2,4 - 3,6 * (11/8 : 33/10 - 5/9) = -2,4 - 3,6 * (11/8 * 10/33 - 5/9) = -2,4 - 3,6 * (10/24 - 5/9) = -2,4 - 3,6 * (5/12 - 5/9) = -2,4 - 3,6 * (45/108 - 60/108) = -2,4 - 3,6 * (-15/108) = -2,4 - 36/10 * (-15/108) = -2,4 - (-1/2) = -2,4 + 0,5 = -1,9
