Answer:

#204,500 = 2.045 xx 10^5#

Explanation:

#100,000# is the 5th power of 10 which can be written as:

#100,000 = 10^5#

#200,000 = 2 xx 10^5#

We have a bit more than exactly #200,000#

#204,500 = 2.045 xx 10^5#

In standard form (also called scientific notation), there is always only ONE digit before the decimal point.
