You can put this solution on YOUR website!
The first rule for scientific notation is that the number (significant figure) has to be between 1 and 10
So, your first number must be 4.09
Then, you add the traditional 10%5Ex
Then count how many spaces to the right you moved the decimal. (4)
Since you moved it to the right, your exponent after the 10 will be negative 4
So, your answer in scientific notation is 4.09%2A10%5E-4
Hope this helps!
