Answer:
5.9 × 10^10
Explanation:
59,000,000,000
The number part has to be between 1 and 10, so it will be 5.9
The decimal point moves from the right of the last zero 10 places to the left to between the 5 and the 9. The exponent is the same number as the number of places the decimal point moves left. The exponent is 10.
59,000,000,000 = 5.9 × 10^10
