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.

**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 .

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 .
