It's 9.231*10^-4.

Explanation:

Recalling fractions notions, we can rewrite this very number as

(9.2cancel(.)3cancel(.)1)/(10000cancel(0)cancel(0)cancel(0)) which is the same as 9.231/10^4=9.231*1/10^4

However, we know that, due to a power rule, that states a^-n=1/a^n, so:

9.231*1/10^4=color(green)(9.231*10^-4)
