1. The speed of light (299792458 m/s) in scientific notation is 2.99792458×108 ≈ 3×108 m/s. 2. 0.00345 would be written as 3.45×10-3 in scientific notation.

Likewise, how do you write 0.0005 in scientific notation?

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Also, what are the rules in writing scientific notation? To create the scientific notation form, start by counting digits left or right from the existing decimal point. The number of digits counted becomes the exponent, with a base of ten. Count left and the exponent is positive; count right, and it is negative.

Considering this, how do you write 0.00001 in scientific notation?

In other words, it is written as a×10n , where 1≤a<10 and n is an integer. To write 0.0001 in scientific notation, we will have to move the decimal point four points to right, which literally means multiplying by 104 .

Which is a correct representation of .000025 in scientific notation?

0008 can be written in scientific notation as 8 x 10-4 or as 8E-4. The power of 10 (-4 in this case) tells you to take the number 8.0 and move the decimal 4 places to the left giving us .
