Answer:

#8*10^6#

Explanation:

#8# million is #8000000#, which in turn can be written as #8*1000000#

This is exactly the idea behind scientific notation: you are interested in the magnitude of the number (in this case millions), and so you express numbers as a certain coefficient times the most significative magnitude.

In this case we literally say "eight millions", which means that the coefficient is #8# and the number is of the order of millions in magnitude.

The last step is to write #1000000# as #10^6#. In fact, each time we multiply by #10# we add a zero at the end of the number, so #1000000# is just a one followed by six zeroes, which means that we multiplied six times by #10#.
