To start, scientific notation is another way to express numbers that are either too big or too small (i.e 0.00000009 or 345,000,000,000).

To put the number 58,000,000 in scientific notation, start off by moving the decimal of the number to the left or right until it is equal to or greater to 1 and less than 10. In this case, you would move the decimal right 7 times so that it looks like this: 5.8
Finally, turn the number into an expression where you multiply the number by 10 to the power of the amount of spaces you moved the decimal to until it was between 1 to 10.
This would be your  5.8*10^7

The answer would be choice b
