Write these numbers in standard notation.
3.05 x 10-3
8.92 x 106

Answer   .00305

                 8920000.

Explanation:

The number 3.05*10⁻³ in standard notacion is 0.00305.

The number 8.92*10⁶ in standard notation is 8,920,000.

Explanation:

Scientific notation is a quick way to represent a number using base ten powers. This notation is used to express very large or very small numbers very easily.

The numbers are written as a product:

a * 10ⁿ

where:

In numbers where the exponent of ten is negative, like in this case of 3.05*10⁻³, you must move the comma to the left as many positions as the exponent marks. After moving the comma the first place to the left, there is a zero followed by the comma and behind the figures we had in scientific notation. Then, for each place that is missing, you have to add a zero to the left, being at all times behind the comma. So, in this case, the number 3.05*10⁻³ in standard notacion is 0.00305.

In numbers where the exponent of ten is positive, you must move the comma to the right as many positions as the exponent that has the ten mark. If you don't have more places to move the comma but we still have positions to move, then you will have to add zeros for each missing position. So, in this case, the number 8.92*10⁶ in standard notation is 8,920,000.
