Question

Just a quick question to refresh my memory on exponents..

Answer 1

If you have something like \[3x ^{-4}\] is it still written like this, or would you do something to keep it from being a negative exponent?

Answer 2

Your
\[3x ^{-4}\]

Answer 3

is fine as is. However, if you are told that your exponents must be positive, use the following rule to rewrite that expression:\[x ^{-a}=\frac{ 1 }{ x^a }\]

Answer 4

Therefore,
\[x ^{-4}=?\]

Answer 5

So I could write it as \[\frac{ 3 }{ x^4 }\]

Answer 6

Because that is what I did originally.

Answer 7

Yes, your original
\[3x ^{-4}=\frac{ 3 }{ x^4 }\]

Answer 8

Okay, thank you so much! :)
