a) ( x+1 )(x2 – x + 1) + (1- x)3 d) (x- 5)2 – 3x( x2 – 1)
b) (2x-1)3 – (x+2)2 e) (2+ x)3 + (x -4 )2
c) (x+3)3 – (x+5)(x-5)


2.Oblicz:
a) 2 ∙(0,3)-1 + 14 ∙81/3 – 12 ∙ 27 -1/3=
b) 1/2 ∙2162/3 + (5,27 -3)0 – 810,75∙(0,5)-1 =
c) 5log_9⁡2 + 2log_9⁡〖1/4〗 =
d)〖 log〗_7⁡12 - log_7⁡2 =
e) 3log⁡3 +2 log⁡2 - log⁡6 =

3. Oblicz:
