Answers are:

3.07 * 10^4 = 30,700.

3.07 * 10^-4 = 0.000307.

3.07 * 10^-6 = 0.00000307.

3.07 * 10^6 = 3,070,000.

1) 10^4 = 10 * 10 * 10 * 10.

10^4 = 10,000.

3.07 * 10^4 = 3.07 * 10,000.

3.07 * 10^4 = 30,700.

2) 10^-4 = 1 : (10 * 10 * 10 * 10).

10^-4 = 1 : 10,000.

10^-4 = 0.0001.

3.07 * 10^-4 = 3.07 * 0.0001.

3.07 * 10^-4 = 0.000307.

3) 10^-6 = 1 : (10 * 10 * 10 * 10 * 10 * 10).

10^-6 = 1 : 1,000,000.

10^-6 = 0.000001.

3.07 * 10^-6 = 3.07 * 0.000001.

3.07 * 10^-6 = 0.00000307.

4) 10^6 = 10 * 10 * 10 * 10 * 10 * 10.

10^6 = 1,000,000.

3.07 * 10^6 = 3.07 * 1,000,000.

3.07 * 10^6 = 3,070,000.
