Question

2 Calculează suma, diferenţa şi produsul numerelor a şi b, ştiind că:
a= 15-3 X 6:(3x3x3:3+0:5) + 30:03:3+5) =
b = 25+ [7 x 2 x 18:2-5 x (5 x 4 - 36:3)] =

Answer 1

Răspuns:

a=15-3*6:(3*3*3:3+0:5)+(30*3:3+5)

=15-3*6:(27:3+0:5)+(90:3+5)

=15-3*6:(9+0)+(30+5)

=15-3*6:9+35

=15-18:9+35

=15-2+35

=13+35

=48

b=25+[7*2*18:2-5*(5*4-36:3)]

=25+[7*2*18:2-5*(20-12)]

=25+(7*2*18:2-5*8)

=25+(14*9-40)

=25+(126-40)

=25+86

=111

Explicație pas cu pas:

111-48=63

111+48=159

111*48=5328
