Answer 1

Răspuns:

a) a= 2.5•1.8

a=4.5

b=1.35+0.15

b=1.5

N=4.5+1.5

N=6

N²=36

b) a= 0.8²

a=0.64

b=9-7.54

b=1.46

N=0.64+1.46

N=2.1

N²=4.41

c) a=1.3²

a= 1.69

b=0.3•1.6-0.17

b=0.48-0.17

b=0.31

N=1.69+0.31

N=2

N²=4

d) a=2.17•3-6.5

a=6.51-6.5

a=0.01

b=0.3²

b=0.09

N= 0.01+0.09

N=0.01

N²= 00.01

Succes si la alte teme✌️
