Answer:
7. 2b and b are like terms,
and 3
are like terms
8. 6 and 7 are like terms, 2n and
are like terms
9. m and 2m are like terms, 3³ and 2 are like terms
10. 6³ and 6² are like terms, y³ and 5y³ are like terms
Explanation:
- The like terms are the terms that have the same variable with the same power
- All numerical rational terms are like terms
- The numerical terms with the same radical are like terms
Let us solve from No. 7 to No. 10
#7
∵ The terms are 2b,
, b,
, 3
, 2x²
∵ 2b and b have the same variable and the same power
∴ 2b and b are like terms
∵
and 3
have same variable b and same power 6
∴
and 3
are like terms
#8
∵ The terms are 6, 2n, 3n², 6m²,
, 7
∵ 6 and 7 are numerical rational terms
∴ 6 and 7 are like terms
∵ 2n and
have the same variable and the same power
∴ 2n and
are like terms
#9
∵ The terms are 10k², m, 3³,
, 2m, 2
∵ m and 3m have the same variable and the same power
∴ m and 2m are like terms
∵ 3³ and 2 are numerical rational terms
∴ 3³ and 2 are like terms
#10
∵ The terms are 6³, y³, 3y², 6², y, 5y³
∵ 6³ and 6² are numerical rational terms
∴ 6³ and 6² are like terms
∵ y³ and 5y³ have the same variable and the same power
∴ y³ and 5y³ are like terms
