Respuesta :

[tex] \cfrac{b^m}{b^n}=b^{m-n} [/tex]

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]
