What is 2,300,000 in scientific notation?

23 x 10^5

2.3 x 10^6

2.3 x 10^-6

230 x 10^4

Answer explanation

The number before the "x" or multiplication sign should ALWAYS be between 1-10.

So we moved the decimal 6 times to get to 2.3 (which is between 1-10). That is why our exponent is 6.

The exponent is a POSITIVE 6 because positive exponents mean the original number was way bigger than 1. Which it is... 2,300,000 is a number way bigger than 1.
