(ab)^n = a^n b^n
So,
(8.03 x 10^4) ^-4
= 8.03^-4 x (10^4)^-4
= (2.405 x 10^-4) x 10^-16
= 2.405 x 10^-20
Could you please show me how you got the results of the 3rd & 4th line?
(2.405 x 10^4) x 10^-16
2.405 x 10^-20

When I solve I get these results:
3rd line) = 4157.7864 x 10^-16
4th line) = 4.1577864 x 10^-19

Thank you!
