[tex] 0.00049=4.9\cdot10^{-4} [/tex]

Hello!


Scientific notation is a number 1-10 multiplied by [tex] 10^{x} [/tex].


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 [tex] 10^{4} [/tex]. 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([tex] 10^{-4} [/tex])


I hope this helps!
