Simplify, leave no negative...?

Question

(9x^-4)^-1

Answer 1

i think this is how you do it

you first multiply the to exponents like so

(9x^-4)^-1=9x^4

and thats all the farther you can simplify it

so yes, leave no negative

Answer 2

The outside -1 makes it

1 / 9x^-4

And the inside -4 makes it

1 / 9*(1/x^4) which makes

x^4 / 9

All positive!

And BTW, a good check for this is to let x=2 and punch that into the original equation and then the solution. You'll get exactly the same answer.

Have a good day!

Answer 3

= 1 / (9x^-4)

= x^4/9
