Question 232051: (b^-4y+7)b^y I am to simplify and I am stuck. I was told no variables raised
------------- to the neg power..they belong on the bottom so here is my
b solution. Is it right?
(b^7)(b^y)
---------
b^4y

You can put this solution on YOUR website!
[(b^(-4y+7))b^y]/b
I am to simplify and I am stuck.
I was told no variables raised
to the neg power..they belong on the bottom so here is my
solution. Is it right?
(b^7)(b^y)
---------
b^4y
======================================================
= [(b^(-4y)(b^7)(b^y)]/b
---
= [b^(-3y)(b^7)/b
---
= [b^(7)]/[b^3y]
---
= [b^7]/[b^(3y)]
=========================
Your answer is correct if you take one more step.
=========================
