Answer: 3 x 10^6
This is the number 3,000,000 aka 3 million
=======================================================
To find this answer, we divide the two values (large/small)
(9 x 10^12)/(3 x 10^6)
(9/3) x 10^(12-6)
3 x 10^6
We divided the stuff out front like normal (9/3 turns into 3) and we subtract the exponents when dividing the 10^12 over 10^6. The general rule is that
(a^b)/(a^c) = a^(b-c)
The result 3 x 10^6 is in scientific notation. It represents the number 3,000,000 aka 3 million. While 9 x 10^12 represents 9,000,000,000,000 which is the number 9 trillion.
