Which of these expressions cannot be simplified by combining like terms? 5ab3+7−3a2b2+a3b−10 5ab3+3a2b2+a3b−10 5ab3+2b(3ab2)+a3b−10 5a3b3+3a2b2+a3b3−10ab

The answer is: is B.

Let's put a letter to each option in order to make the option identification easier:

A -

B -

C -

D -

Calculations:

A

We combined like terms for -10 and 7.

B

There is no way to simplify by combining like terms.

C

We simplified by combining like terms for

D

We simplified by combining like terms for

Therefore, the expression that can not be simplified by combining like terms is B.
