Answer:
140,620,000
Step-by-step explanation:
There are two types of standard form. The one above (given to you) is the normal standard form. However, there is another one. This one would look like:
140,620,000 = 1.4062 x 10^8
Remember that in this standard form, you must move the decimal to just after the first place value, and the amount of moves you made for the decimal is the amount in the power over 10.
