Scientific notation is written as #.## x 10^#.
Our number, 3,050,000, needs to be written in scientific notation.
The best way to write scientific notation is by "#.## x 10^#".
In this case, it will be 3.05 x 10^#, # being the amount of times we move the decimal to the right. We have moved it 6 times to the right, so our expression is:
3.05 x 10^6.
I hope this helps!
