Question

Se dau numerele : a =[1+(2+3*4)*5+4]:3-2*2
b=(9+8-7)*6:(7+8-9)
c=44:(44:4)*4+4-(4+4*4)
Calculeaza : c*(a-b)

Answer 1

a=[1+(2+3x4)x5+4]:3-2x2=(1+14x5+4):3-4=(1+70+4):3-4=75:3-4=25-4=21
c=44:(44:4)x4+4-(4+4x4)=44:11x4+4-20=4x4+4-20=16+4-20=20-20=0
b=(9+8-7)x6:(7+8-9)=10X6:6=60:6=10
cX(a-b)=0x(21-10)=0x11=0

Answer 2

a=[1+(2+3x4)x5+4]:3-2x2
a=(1+14x5+4):3-2x2
a=75:3-2x2
a=25-4=21

b=(9+8-7)x6:(7+8-9)
b=10x6:6
b=10

c=44:(44:4)x4+4-(4+4x4)
c=44:11x4+4-20
c=4x4+4-20
c=0

cx(a-b)=0
0x(21-10)=0x11=0
