Use scientific notation to find the product of 20.5 × 10^7 and 0.000036."

You can express 0.000036 as 3.6 × 10^-5 (we move the decimal 5 places left)

Then we find 3.6 × 10^-5 × 20.5 × 10^7
The exponents add to become just 10^2.
3.6 × 20.5 = 73.8

73.8 × 10^2 is our answer...
In proper scientific notation, this is 7.38 × 10^3. (the left # should be <10)
In standard notation, this is 7380. (we move the decimal 3 places right)
