Answer:

your answer would be B -5

Step-by-step explanation:

this would be the answer of course because of my thoughtful manner.

The equation [tex](y^{-9})^b = y^{45[/tex] is an exponential equation, the value of b in the equation is -5

How to determine the value of b?

The equation is given as:

[tex](y^{-9})^b = y^{45[/tex]

Evaluate the exponent

[tex]y^{-9b} = y^{45\\[/tex]

Cancel out the common base (y)

-9b = 45

Divide both sides by -9

b = -5

Hence, the value of b in the equation is -5
