## anonymous 5 years ago rewrite the following expression with positive exponents. (38xy)^-9/10

1. anonymous

${(38xy)^{-9} \over 10}={1 \over 10(38xy)^9}$

2. anonymous

it gives me a choice of a,b,c or d and that is not one of the answers

3. anonymous

4. anonymous

Write down the choices.

5. anonymous

the choices are a. 1/(38xy)^10/9, B. (38xy)^9/10, C. (38xy)^10/9, D. 1/(38xy)^9/10

6. anonymous

D.

7. anonymous

In D. The 9/10 is only for (38xy) not the whole equation

8. anonymous

would it still be D

9. anonymous

I'm sry I dont know how to write the equation out the way it shows me

10. anonymous

Oh the problem was $(38xy)^{-9 \over 10}={1 \over (3xy)^{9 \over 10}}$

11. anonymous

yes that is the way it looks, Ok was just making sure

12. anonymous

So yeah the answer is still D :)
