1. oblicz warości wyrażenia:
a) (-1/3)²* -3*|-1/3|+6
b) 3/4*(2/3)²- 1/2*(-4)³
2.oblicz i miejsca kropek wstaw odpowiedni znak<,>lub=.
a) (-3)².....6²/2
b) 3(do potęgi 4)-2(do potęgi 4)....(-6)(do potęgi 0) +4³

1.
a) (-1/3)^2 * (-3) * | -1/3| + 6 = 1/9 * (-3) * 1/3 + 6 = 1/9 * (-1) + 6 = -1/9 +6 = 5 i 8/9
b) 3/4 * (2/3)^2 - 1/2 * (-4)^3 = 3/4 * 4/9 - 1/2 * (-64) = 1/3 - (-32) = 1/3 + 32 = 32 i 1/3
2.
a) (-3)^2 = 9 .. <..... 6^2 / 2 = 36/2 = 18
b) 3^4 - 2^4 ... = ... (-6)^0 + 4^3
81 - 16 ... = .... 1 + 64
65 ....... = ..... 65
