Among the given expressions, only
has a term with a base of 8, as it represents the number 8 raised to the power of 4.
An expression with a term having a base of 8 is
. To understand this, let's break down each expression:
1. 8m: This expression has a coefficient (8) multiplied by a variable (m), but the base is the variable 'm,' not the number 8.
2. 3xy + 8: In this expression, the term with '8' is a constant term added to the product of 3xy. The base of the term is the constant value 8.
3.
This expression contains a term with a base of 8, where the variable 'z' is raised to the exponent 8. The base here is the variable 'z,' not the number 8.
4.
: This expression represents the number 8 raised to the power of 4. Here, the base is indeed 8, and the exponent is 4. This term is a numerical expression, and the base is the number 8.
In summary, the expression with a term having a base of 8 is
because it represents the number 8 raised to the power of 4.
