b) 34.(-84)+17.(-32)

Giúp mình nha !!!

Answer 1

a) -326 - (115 - 326)

= -326 - 115 + 326

= (326 - 326) - 115

= 0 - 115

= -115

b) 34.(-84) + 17.(-32)

= 17 .2.(-84) + 17.(-32)

= 17.(-168) + 17.(-32)

= 17.(-168 - 32)

= 17.(-200)

= -3400

b) 34.(-84)+17.(-32)

=17.2.(-84)+17.(-32)

=17.(-168)+17.(-32)

=17.[(-168)+(-32)]

=17.(-6200)

Answer 3

a)-115

b)-3400

Answer 4

a,-326-(115-326)=-326-115+326=-115

b,34x(-84)+17x(-32)=2x17x(-84)+17x(-32)=17x(2x(-84)-32)=17x(-200)=3400
