Hint: First determine the number of digits in the given number. We will move the decimal point from 318600000000.00 to left after the digit 3. Also, raise the power of 10 to the number of places the decimal has moved to left.

Complete step-by-step answer:
We have to find the scientific form of 318600000000.
Scientific is a form of writing a number in a different way such that the number is read easily.
We will write the given number using the powers of 10.
We will place the decimal point just after one digit of the number. The power of 10 will be the number of digits after the first digit.
That if we place a decimal point after 3 in the given number, there are 11 digits after 3 in the given number.
Hence, we will raise 10 to the power of 11 after placing decimal after 3 in the number, 318600000000
When we move the decimal point to the left, the power of 10 is positive.
In the number, 318600000000 the decimal is placed such that 318600000000.00 and we will now place the decimal after digit 3.
Hence, the scientific notation is $3.186 \times {10^{11}}$.

Note: We can convert any number in scientific notation which makes it easy to read. When we move the decimal point to the left, the power of the 10 increases but if we move the decimal point to the right, the power of 10 decreases.
