## clarkexo 3 years ago show in negative exponent: 2/a

• This Question is Closed
1. TuringTest

$a^{-b}=\frac1{a^b}$

2. TuringTest

what is the exponent on a? that is your b

3. clarkexo

there is no exponent on a

4. Kashan

simple as I told you.. invert it.. it will be (a/2)^-1

5. clarkexo

hm..it's saying its wrong

6. Kashan

not its not.. (a/2)^-1 is in negative exponent.. you can further expand it like.. (a^-1)/(2^-1)

7. Kashan

if question is to show it in negative exponent then my answer is perfectly all right..

8. clarkexo

the answer was 2 x a^-1

9. Kashan

so it means that it was to show only "a" in negative exponent.. not the whole value..

10. clarkexo

It just said show the question in a negative value, idk :s

11. Kashan

you can solve it like... (2/a) = 2x (1/a) when you'll invert "a" you'll get that answer.. 2x(a)^-1

okay, ty i have 2 more questions
