Question

Verify that (a+b)+c=a+(b+c)by taking a=_7 b=4and c=_2\11 solve

Answer 1

Step-by-step explanation:

(a+b)+c=a+(b+c)

or,(7+4)+2/11=7+(4+2/11)

or,11+2/11=7+((11×4)+2)/11

or,((11×11)+2)/11=7+(44+2)/11

or,(121+2)/11=7+46/11

or,123/11=((7×11)+46)/11

or,123/11=(77+46)/11

or,123/11=123/11

thus , verified
