Question

Daca a=16, b=9, c=17, fa
a+b a+c b+c a ori b, a ori c, b ori c
a+b+c, a+b-c, b+c-a, ab + ac, ab+bc, bc+ac, a(b+c), b(a+c), c(a+b)

Answer 1

Răspuns:

a+b = 16+9= 25

a+c= 16+ 17= 33

b+c= 9+ 17= 26

Nu mai scriu cat e a cat e b pun direct calcul.

a×b= 144

a×c= 272

b×c= 153

a+b+c= 42

a+b-c= 8

b+c-a= 10

ab+ac= 416

bc+ac= 425

a(b+c)= 416

b (a+c)= 297

c(a+b)= 425
