Odpowiedź:
a)
1/2+15/10= 5/10+15/10=20/10=2
32/10-4/3=48/15-20/15=28/15=1 i 13/15
73/10-102/25= 365/50-104/50=261/50=5 i 11/50
b)
24/10*3/8=9/10
11/4*100/275=275/275=1
25/10*5/2=25/4=6 i 1/4
c)
(2/10+1/2)^2= 7/10^2=49/100
(7/4-85/100)^2=(175/100-85/100)^2=90/100^2=81/100
(31/5-594/100)^2=(620/100-594/100)^2=676/10 000
d)
(5/10)^3+(1/3)^2=125/1000+1/9=236/1000
(1/10)^3+(1/5)^2= 1/1000+1/25=41/1000
(14/10)^2+(4/5)^2=196/1000+16/25=836/1000
