Scientific notation is basically a number between 1 and 10 multiplied by 10 to the power of something.
To find scientific notation, you must first count the number of zeros. There are 9 zeros.
Because the number is a positive number, your exponent will be positive.
After counting all the number of zeros, you are left with the number 123.
Next, you must find a way to simplify this number to inbetween 1 and 10. if you move the decimal place 2 spots to the left, 123 becomes 1.23.
Next, you add the number of spots you moved the decimal and the number of zeros to the new number you have created.
9 zeros + 2 moved spots = 11
Answer:
1.23*10^11
