The problem can be rearranged thusly:
(180 / 2) times (10^8 / 10^4)
The first part is simply:
180 / 2 = 90
In the second part you subtract the values of the exponents when dividing:
10^8 / 10^4 = 10^(8-4) = 10^4
Putting the two parts together gives you the answer:
90(10^4)
Which can be reduced to:
9(10^5)

divide the 180 and the 2 , then the 10^8/10^4 by subtracting exponents:
= 90 x 10^4
= 9.0 x 10^5
that's it! :)
