Question

Calculati produsul dintre dublul lui. A si triplul lui. B daca: a=[(20+5:5)*10-10]:10. B=[(20:4)*5+20*2]-4

Answer 1

a=[(20+1)*10-10]:10
a=(21*10-10):10
a=(210-10):10
a=200:10
a=20

b=[5*5+40]-4
b=25+40-4
b=61

2a*3b=?
2*20*3*61=
40*183=
7320

Answer 2

A=[(20+5:5)*10-10]:10=[(20+1)*10-10]:10=(21*10-10):10=(210-10):10=200:10=20
B=[(20:4)*5+20*2]-4=(5*5+20*2)-4=(25+40)-4=65-4=61

2A*3B=2*20*3*61=7320
