Answer 1

Răspuns:

10. a. 5/6

b. 4/7

c.8/9

d.5/7

e. 9/10

f. 7/12

g. 15/8

h. 14/5

14. a. n= 15+10-9=25-9=16, √16=4

b.n=18+5+13=23+13=36, √36=6

c. n=3·16-4+20=48-4+20=44+20=64, √64=8

d. n=18-7+5·14=11+70=81, √81=9

15. a. n=(24+16):10=40:10=4, √4=2

b. n=18:(16-14)=18:2=9, √9=3

c. n=(30+18):12=48:12=4, √4=2

d. n=12·(17-14)=12·3=36, √36=6
