Respuesta :
First you need to add the two years together to get 91,800,000 from there you can start to turn it into scientific notations.
Then start out by putting an imaginary decimal point at the end so you have 91,800,000.
From there you need to move the decimal next to the 9 so 7 spots to the left.
Now that you have the number and the exponent you just put them together.
You should have 9.18 x 10^7

Answer:
What you need to do is to find a multiple of 20 and 16 in other words a number that can multiply into 20 and 16. You have 2 and you have 4. So now this is how it looks like.
Either:
4(5+4) Or
2(10+8)
