Answer:
1. 5,750,000,000
2. 0.00068
3. 520,000,000
Explanation:
After the decimal point, the amount of numbers have to be the same amount as the exponents. So it wouldnt be 575000000000, but instead it would be 5750000000. Because 5.75, the numbers after the decimal point count, so instead an easier way would be to subtract the number of exponents ( 5.75 x `0^9) with the amount of numbers after the decimal point. So 9 - 2 = 7. So there should be 7 zeros after the number. If it doesnt make sense, dont worry, youll get the hang of it.
