625 000
A number written in scientific notation usually expresses a very large or very small number by writing its value as a product of 10 to some power. Let's look at some examples.
Scientific Notation | Standard Notation |
---|---|
5 * 10^(10) | 5 0 000 000 000 |
5 * 10^5 | 5 00 000 |
5 * 10^1 | 5 0 |
5 * 10^0 | 5 |
5 * 10^(- 1) | 0.5 |
5 * 10^(- 5) | 0.00005 |
5 * 10^(- 10) | 0.0000000005 |
6.25* 10^5 In this case, the exponent is positive5, so we should move the decimal five places to the right.
We can see that the standard form of 6.25* 10^5 is 625 000. Scientific Notation:& 6.25* 10^5 Standard Form:& 625 000
