Answer:

= 4.5 × 10⁻³

Step-by-step explanation:

The proper format for scientific notation is a × 10ᵇ where a is a number or decimal number such that the absolute value of a is greater than or equal to one and less than ten or, 1 ≤ |a| < 10. b is the power of 10 required so that the scientific notation is mathematically equivalent to the original number.

Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. The resulting decimal number is a.

Count how many places you moved the decimal point. This number is b.

If you moved the decimal to the left b is positive.

If you moved the decimal to the right b is negative.

If you did not need to move the decimal b = 0.

Write your scientific notation number as a × 10ᵇ and read it as "a times 10 to the power of b."

Remove trailing 0's only if they were originally to the left of the decimal point.
