ok i think i mightove missed the day whe learned this soo can u hlp me? O.O

...the directions say simplify each quotient,using a positive exponent.assume each variable does not equal zero (we are reviewing stuff i should have learned)

ex of one of the Q's: b(to the 12th power)over b (to the 4th power)

(i know its silly but my mom doesnt remember hardly anything from math soo i gotta ask for hlp)

You subtract the powers. So it's b to the (12-4) power or b to the 8th power. Does that help?

First, some notation: if you want to write "a to the power of b", write it as a^b. "a divided by b" should be a/b.

Anyways, the rule to remember is that when you divide exponentiated expressions of the same base, you subtract. If you're multiplying, you add. In your example b^12/b^4=b^(12-4).

The reason for this is relatively straightforward if you exand the exponent. For example:
b^3/b^4= (b*b*b)/(b*b*b*b).
Cancelling yields, 1/b=b^(-1)=b^(3-4).

lol thx ^_^ i really need to keep up with my learning lol
