Answer:

#8.205*10^2#

Explanation:

When we write numbers in scientific notation, we want one non-zero digit before the decimal. In our case, we want it after the #8#.

We need to loop it #2# times to the left. This will be our exponent. Since we are looping it left, the exponent will be positive. We get

#bar(ul (| color(white)(2/2)8.205*10^2 color(white)(2/2)|))#

Hope this helps!
