Question

What is the scientific notation of 0.00165?

Answer 1

Answer:

The answer is $1.65*10^{-3}$

Step-by-step explanation:

when writing scientific notation, there must be one number to the left of the decimal point.

To achieve this in this problem, you need to move the decimal point 3 times to the right.

because you are moving the point to the right, the exponent will be negative.

*rule of thumb: moving the decimal to the left will give you a positive exponent, moving to the right will give you a negative exponent*

therefore you answer should be written as:

$1.65*10^{-3}$

hope this helps :)
