Question

help with negative exponent fractions?!
(x+3)^(-1/3)-2(x+3)^(-1/3)=3

Answer 1

would it be u=(x+3^/1/3)^2?

Answer 2

Negative exponent means "inverse" not "negative"

Answer 3

For example

\[x^{-a} = \frac{1}{x^a}\]

Answer 4

In this case

\[(x+3)^{-1/3} = \frac{1}{(x+3)^{1/3}}\]

Answer 5

Which becomes

\[\frac{1}{\sqrt[3]{x+3}}\]

Answer 6

So if you have x to the `negative` a, the negative exponent indicates the `inverse` of x to the a

Answer 7

And just to remember this, you can basically read \(x^{-a}\) as `the inverse of x to the a` rather than say `x to the negative a`
