Odpowiedź:
1.
√49 + ∛27 = 7 + 3 = 10
√(1 7/9) = √16/9 = 4/3 = 1 1/3
2.
(1 1/2)² - 1/2 * (-2)^0 = (3/2)² - 1/2 * 1 = 9/4 - 1/2 = 9/4 - 2/4 = 7/4 = 1 3/4
3.
√3 * √27 = √(3*27) = √81 = 9
∛48 : ∛6 = ∛8 = 2
4.
(-2)^5 : (-2)^4 * (-2)² = -2 * 4 = -8
(2/5)^5 : (-1/5)^5 = (-2/5* 5)^5 = (-2)^5= -32
[(-1)^7]^4 = (-1)^28 = 1
5.
√72 = √(2*36) = 6√2
∛40 = ∛(8*5) = 2∛5
6.
2∛100 = ∛(8*100) = ∛800
5√6 = √(25*6) = √150
