1) 7.15 * 10^6
since the exponent of the scientific notation is positive, move 6 places to the right.
so, 7.15 * 10^6 = 7150000
2) 3.03 * 10^-8
Since the exponent of the scientific notation is negative, move the decimal point 8 places to the left.
so, 3.03 * 10^-8 = 0.0000000303
3) 4.9 * 10^-1
since the exponent of the scientific notation is negative, move 1 decimal place to the left.
so, 4.9 * 10^-1 = 0.49
4) 2.886 * 10^5
since the exponent of the scientific notation is positive, move 5 decimal places to the right.
so, 2.886 * 10^5 = 288600
