Answer:

#1.5984*10^5#

Explanation:

The key realization is that when we write numbers in scientific notation, we want one non-zero digit before the decimal point.

In our example, we need the decimal to be after the #1#, so we must loop it #5# times to the left.

The #5# will be our power of #10#, and since we looped the decimal left, the exponent will be positive. We get

#1.5984*10^5#

Hope this helps!
