Answer :
All the pairs that are like terms are given as follows:
1.) -4n and 18n
2.) 15ab and 2ab
5.) 14h and -3h
What are like terms?
Like terms are terms that share these two features:
- Same letters. (algebraic variables).
- Same exponents.
If two terms are like terms, then they can be either added or subtracted.
The like terms for this problem are given as follows:
1.) -4n and 18n -> algebraic variable of n, exponent of 1.
2.) 15ab and 2ab -> algebraic variable of ab, exponent of 1.
5.) 14h and -3h -> algebraic variable of h, exponent of 1.
For example, the pair in item 3 is of terms that are not like terms, as they have different algebraic variables, f and 1.
