Question

Dacă se poate si formulele de rezolvare
dau coroană ​

Answer 1

Răspuns:

1.a)|5radical7|=5radical7

b)5radical7+3radical7=8radical7

c)3radical7-5radical7=-2radical7

d) nu vad d ul

2.a)|-2radical3|^-1=(2radical3)^-1=radical3/6

b)=-8radical18=-24radical2

c)=-2radical2

d) nu vad d ul

3)radical2=1,41=>a=3×1,41=4,23

radical5=2,23=>b=2×2,23=4,46

deci a<b

4)mg=radical a×b |formula ,dar nu stiu sa o aplic ;(

5)=2radical6×(2radical2+3radical2)+(3radical15):(3radical5-6radical5)

2radical6×5radical2+(3radal15):(-3radical5)

10radical12-radical3

20radical3-radical3

19radical3

6) nu stiu sa l fac.

Sper ca te-am ajutat!
