Answer:
1.5 * 10^8
Step-by-step explanation:
Find the number of digits.
There are nine digits, subtract one, so we raise 10 to the power of 8.
Now, check the digits until it's just a string of zeroes.
We have 15.
Raise the decimal point until there is just one digit above the decimal point.
We have 1.5.
Now, multiply the two.
1.5 * 10^8
