## KrystaRenee What is the simplified form of this expression? –(10)^–1 -1/10 -1/-1^10 1/10 10 one year ago one year ago

1. whpalmer4

$x^{-n} = \frac{1}{x^n}$

2. KrystaRenee

I can't really see what that says.

$\huge x^{-n}=\frac{1}{x^n}$

4. KrystaRenee

I was thinking the last option.

5. whpalmer4

Think again :-)

no thats a trap use the formular above in our case we have$x^{-1}=\frac{1}{x}$

7. KrystaRenee

Or the third option.

8. whpalmer4

Your equation is $-10^{-1} = \frac{1}{-10^1}$Remember that $x^1 = x$

9. whpalmer4

So $-10^1 = -10$

10. KrystaRenee

Yes.

11. whpalmer4

What does that mean the answer is?

12. KrystaRenee

I'm getting confused. I guess the first one.
