All numbers in scientific notation or standard form are written in the form

[tex]m\cdot10^n[/tex]

where m is a number between 1 and 10 and the exponent n is a positive or negative integer.

To convert 64500 into scientific notation, follow these steps:

1. Move the decimal 4 times to left in the number so that the resulting number, m = 6.45, is greater than or equal to 1 but less than 10

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

n = 4

3. Write in the scientific notation form, m × 10^n

= 6.45 × 10^4
