#2.8*10^9#

Explanation:

When we write numbers in scientific notation, we want one non-zero digit before the decimal. This means we'll have the decimal between the #2# and the #8#.

We need to loop the decimal #9# times to the left. This will become our power of #10#.

Since we looped left, the exponent will be positive. We have

#2.8*10^9#

Hope this helps!
