Converting to Scientific Notation
To express the number 172 in scientific notation, we need to represent it as a product of a number between 1 and 10 and a power of 10.
Here are the steps to convert the number:
- Identify the decimal place in the number. For 172, the decimal is at the end (172.0).
- Move the decimal point to the left until only one non-zero digit remains to the left. For 172, we move it two places to the left, giving us 1.72.
- Count the number of places the decimal was moved. In this case, it is 2 places.
- Since we moved it to the left, the exponent for the power of 10 will be positive. Thus, we write it as 10^2.
Putting it all together, 172 in scientific notation is written as: 1.72 x 10^2.
