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!
