Question

Convert 84170 seconds to scientific notation

Answer 1

First, put a point after the first digit: 8.4170.

Next, count the number of decimal places: 4170 is four decimal places. So, the scientific notation is

$$8.4170\cdot10^4$$

We can legally drop zeroes at the end of the decimals:

$$8.417\cdot10^4$$
