Which of these expressions CANNOT be simplified by combining like terms?

CLEAR CHECK

6fg3+4−4f2g2+f3g−12

6fg3+2f(2fg)+4f2g−10

6fg3+5f2g2+f3g−7

6f3g3+7f2g2+4f3g3−10fg

Step-by-step explanation:

An expression is said to be like, if there are only constants term in it, otherwise degree of variables in two distinct terms are same.Starting from option (1)

1. As, 4 and -12 are like terms, they are combined to get  -8.

2. As, 2 f( 2 f g) and  are like terms, so they can be combined to get

.3. as,there are no like terms, so, we cannot simplify this expression.→→→Correct Option,This expressions Cannot be simplified by combining like terms

4. As,  are like terms.They can be combined to get a unique term.

won't that be plagrisim thought?
