Question

Convert 0.00049 to scientific notation

Answer 1

$0.00049=4.9\cdot10^{-4}$

Answer 2

Hello!

Scientific notation is a number 1-10 multiplied by $10^{x}$.

As this number is less than one, we will use a negative exponent. We want to get a number between one and ten. To do so we multiply our number by $10^{4}$. This gives us 4.9.

To show that this represents our number, we will use a negative exponent and get our answer below.

4.9($10^{-4}$)

I hope this helps!
