calculeaza:3×a-3×b+3×c stiind ca;a=(5+5+2-2:2)×2;b=[36-16/(25/5-12/3)]/5-4:c=7+3×[2-27/(5×5+2/1)]

Răspuns :

a=(5+5+2-1)×2
a=(12-1)×2
a=11×2
a=22
b =[36-16:(25:5-12:3)]:5-4
b=[36-16:(5-4)]:5-4
b=(36-16:1):5-4
b=(36-16):5-4
b =20:5-4
b=4-4
b=0
c=7+3×[2-27:(5×5+2:1)]
c=7+3×[2-27:(25+2)]
c=7+3×(2-27:27)
c=7+3×(2-1)
c=7+3×1
c=7+3
c=10
3×22+3×0+3×10=
66+0+30=96
sper ca te-am ajutaya
