Question

Identify the like terms in the expression 7a²bc and mention their numerical coefficients.

a) Like terms: a²,bc, Numerical coefficients: 7
b) Like terms: 7a,bc, Numerical coefficients: 2
c) Like terms: 7a²b,c, Numerical coefficients: b
d) Like terms:7a²bc, Numerical coefficients: 11

Answer 1

In the expression 7a²bc, there is only one term; hence, the only like term is 7a²bc itself. The numerical coefficient of this term is 7.

Step-by-step explanation:

To identify like terms in the expression 7a²bc, we need to look for terms that have identical variable parts, meaning they have the same variables and the same exponents. In the given expression, there is only one term, so there are no like terms to be listed apart from the term itself. The numerical coefficient of this term is 7, and it is multiplied by the variables a (squared) and b and c (both to the first power). Therefore, the like term is 7a²bc, and the numerical coefficient is 7.
