please give me proper answer
it's compulsory​

Answer 1

Step-by-step explanation:

L.H.S R.H.S

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

3 + (4 + 5) (3 + 4) + 5

3 + 9 7 + 5

12 12

L.H.S = R.H.S

Hence proved

Reason because asscociative property come under addition

HOPE IT HELPS ;)

Answer 2

Answer:

L.H.S R.H.S

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

3+(4+5) (3+4)+5

3+9 7+5

12. 12.

L.H.S = R.H.S

Hence proved.

I used Associative Property under Addition.

I hope you understand this answer to you.
