Question

express the following in scientific notation 68585

Answer 1

Answer:

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 68585 into scientific notation, follow these steps:

Move the decimal 4 times to left in the number so that the resulting number, m = 6.8585, is greater than or equal to 1 but less than 10

Since we moved the decimal to the left the exponent n is positive

n = 4

Write in the scientific notation form, m × 10n

= 6.8585 × 104

Therefore, the decimal number 68585 written in scientific notation is 6.8585 × 104 and it has 5 significant figures.
