Which of these expressions CANNOT be simplified by combining like terms?
The answer:
to simplify the terms , the terms must be similar like ab and 3ab the result will be 4ab.
So for our giving options:
1) 5ab3 +7 - 3a²b2 + a'b – 10
2) 5ab3 + 3a2b2 + ab - 10
3) 5ab3 + 3a2b2 + a363 - 10ab
4) 5ab3 + 26(3ab2) + a’b – 10
so, as shown at the options:
option 1) Can be simplified to 5ab3 - 3a²b2 + a'b – 3
becuse it has only two like terms {7 - 10}
Option 2) CANNOT be simplified
Becuse, it is not contain like terms
Option 3) CANNOT be simplified
Becuse, it is not contain like terms
Option 4) CANNOT be simplified
Becuse, it is not contain like terms
So, the answer is all: All expressions CANNOT be simplified by combining like terms except the first expressions.
