Just to be clear, is this what you mean? \[\frac{12a^{5}}{2a^{8}}\]

Okay, are you able to solve it *with* negative exponents?

\frac{top}{bottom} Do that in the Equation editor, or within \[ and \ ]

nope it said do not use neg exponents and the 5 is 5 and the 8 is 8

I know, but once we get to the final answer *with* negative exponents, we can get rid of them by rewriting the answer.

Wait, are you saying it's to the power of 5 and 8?

Which is correct—top or bottom? \[\frac{12a^{5}}{2a^{8}}\] \[\frac{12a^{5}}{2a^{8}}\]

Okay, great. And there are no brackets, right? It's not \((12a)^{5}\)?

So, to start, are you able to simplify the equation?

I could not find an exmaple in the book like mines so one of the problems in the exercise is like my real problem i need help to figure it out so i can solve mines

Do you know how to simplify exponents?

geoffb Group TitleBest ResponseYou've already chosen the best response.1
When dividing like bases (in this case, \(a\)), you subtract the bottom exponent from the top. So, \(a^{(5)(8)}\).

As for your numeric constants, you just divide them (\(12 \div 2\))

do I do the samething if my problem has 12 x top and 8y bottom
 2 years ago

geoffb Group TitleBest ResponseYou've already chosen the best response.1
Do you mean like: \(\Large{\frac{12x}{8y}}\) ? No, those are different variables, so you cannot divide one by the other.
 2 years ago

geoffb Group TitleBest ResponseYou've already chosen the best response.1
You can simplify the numbers \(\Large{\frac{12}{8} = \frac{3}{2}}\), but that's all.

skylar87 Group TitleBest ResponseYou've already chosen the best response.0
yes with 6 at the top and 10 at the bottom
 2 years ago

geoffb Group TitleBest ResponseYou've already chosen the best response.1
Ahh, so: \[\frac{12x^{6}}{8y^{10}}\] Nope, all you can simplify in this case is 12/8.
 2 years ago

geoffb Group TitleBest ResponseYou've already chosen the best response.1
Yes, with the same exponents.

so there isn't any steps to break it down because my teacher keep saying show your work

If they're different variables, you can't simplify them further.

geoffb Group TitleBest ResponseYou've already chosen the best response.1
The only "work" you could show is dividing both the top and bottom by 4, to simplify your numeric fraction.
