Answer 2

Given : 3a²b,-5a²b,10a²b,-7a²b

To Find : Add all term

Solution:

3a²b,-5a²b,10a²b,-7a²b

Adding all

3a²b +(-5a²b) + 10a²b +(-7a²b)

(-)(-) = +

(+)(-) = -

(-)(+) = -

(+)(+) = +

3a²b  -5a²b + 10a²b -7a²b

Rearrange the order

3a²b + 10a²b  -5a²b -7a²b

= 13a²b  -12a²b

= a²b

3a²b +(-5a²b) + 10a²b +(-7a²b)   =  a²b
