Answer 2

Answer : (a) 18abc.

Step-by-step-Explanation :-

The like terms always add to each other.

First expression :-

=) 5a + 5a + 5ab + 5ab

Here, like terms are 5a, 5a & 5ab, 5ab.

So, add these like terms.

=) (5a + 5a) + (5ab + 5ab)

=) 10a + 10ab

Similarly, add the like terms of second Expression, i.e. :-

=) 6abc, 6abc, 6abc

Here, all the terms are similar.

=) 6abc + 6abc + 6abc

=) 18abc

Hence, the answer is (a) 18abc.
