1/5^9= 5.12 x 10^-7

Work backwards: 1/5 is the conjugate of 5 therefore, if 1/5 is raised to the 9th power the opposite of that is -9.

5^-9= 5.12 x 10^-7

your answer: B
Um.... Do you mean that my answer is correct or not?
I agree that B is the correct answer.

(1/5^9) = 5^?

(0.000000512) = 5^(?)

When 5 is raised to the -9 power, it equals the same as 0.000000512.

5^-9 = 0.000000512

0.000000512 = 0.000000512

So, B is the correct answer. I hope this helps! :)
Thank you both.
