570000000 = 5.7×10^8

2.32 * 10-7

The ten is to the negative seventh power because you have to move the decimal to the left 7 places to get one whole number.

0042000 = 42000 = 4.2*104.

It is: 1.416*10^8

4.89x10^4

8.35 X 106

-------------

The zeroes are superfluous here. Except for counting places. They reappear when the number is written in standard form.

It is 64^2.

It is: 6.9*10-3

15 billion = 1.5 x 10^10 or 1.5e+10

3.0582 x 109

8.8888 X 106.

Molecular biology, quantum physics, cosmology and physical chemistry are four examples.

6.23 × 10-4

3*10 to third power + 2

It is 9.045*10^(-3)

Move 6 decimal places from the starting point to get 5.6 x 10-6. We obtain the negative exponent due to the leading nonzero digit 5 in the millionths place.

It is: -2.2*10^12
