Answer:
The expression that is equivalent to the given expression is:
A. [tex]b^{m-n}[/tex]
Step-by-step explanation:
We are given a algebraic expression in terms of b as:
[tex]\dfrac{b^m}{b^n}[/tex]
We know that the expression is evaluated as:
[tex]\dfrac{b^m}{b^n}=b^{m-n}[/tex]
Hence, the expression is:
[tex]b^{m-n}[/tex]
