d) + =

e) =

f) (dam ma być 2 i 2/3 ;d)

dzięki z góry ;*

Answer 1

a)2 2/3 : (3 1/3 + 1 1/2)=8/3 : (3 2/6 + 1 3/6)=8/3 : 29/6 = 8/3 * 6/29 =16/29

b) 2^3 - (1 1/2)^2= 8 - (3/2)^2= 8 - 9/4 = 6 3/4

c)(1 2/3)^-2 - 1^-3=(5/3)^-2 - 1=25/3 - 1=8 1/3 - 1=7 1/3

d) +  =4+(-3)=1

e) =1:5=0   (tego nie jestem pewien )
