Write 230,000,000,000 in scientific notation.

To write this in scientific notation, move the decimal place at the end of this number 11 spaces to the left so that you're left with a number in between 1 and 10: 2.3 (you don't need to write the zeros as they are now irrelevant.

Because you moved 11 spaces to the left, you write 10^11.

Putting these two together, you get 2.3 x 10^11

2.3 x 10^11
