Answer 1

\[a^{-b}=\frac1{a^b}\]

Answer 2

what is the exponent on a?
that is your b

Answer 3

there is no exponent on a

Answer 4

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

Answer 5

hm..it's saying its wrong

Answer 6

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

Answer 7

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

Answer 8

the answer was 2 x a^-1

Answer 9

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

Answer 10

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

Answer 11

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