The correct way to write (1.3 times 10^{-7}) in standard notation is 0.00000013.
### Explanation:
The notation (1.3 times 10^{-7}) means you move the decimal point 7 places to the left (because of the negative exponent). Starting with 1.3:
1. Move the decimal left one place to get 0.13.
2. Move it left six more places to get 0.00000013.
So, the final answer is 0.00000013.
