Hello! Welcome to Brainly! Let's solve together. :)
To put a number into scientific notation, you multiply it by a power of 10 that will make it a digit 1-10.
As you can see, we can divide by 10, or multiply by 1/10 to get us to 1.3, which is between 1 and 10. How would we get 1.3 to 13? We would multiply by 10!
This gives us our answer below.
1.3(10)
