All numbers in scientific notation or standard form are written in the form m × 10n, where m is a number between 1 and 10 ( 1 ≤ |m| < 10 ) and the exponent n is a positive or negative integer.
To convert 0.0002 into scientific notation, follow these steps:
Move the decimal 4 times to right in the number so that the resulting number, m = 2, is greater than or equal to 1 but less than 10
Since we moved the decimal to the right the exponent n is negative
n = -4
Write in the scientific notation form, m × 10n
= 2 × 10-4
Therefore, the decimal number 0.0002 written in scientific notation is 2 × 10-4 and it has 1 significant figures.
