In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data
scientific notation
6.15 x 10^7
standard form = ?
Step 02:
scientific notation to standard form.
6.15 x 10^7 = 61500000
If the exponent is positive, you must move the decimal point 7 spaces to the right.
The answer is:
6.15 x 10^7 = 61500000
