How is 123,000,000,000 expressed in scientific notation?

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

Answer

12.3^{-10}

Step-by-step explanation:

count how many zeros their are and if it goes to the left its negative if it goes to the right its positive.
