Question

1. write 1,243,000 in scientific notation.

Explanation:

Step1: Move decimal point

Move the decimal point to get a number between 1 and 10. For 1243000, moving the decimal 6 places to the left gives 1.243.

Step2: Determine exponent

Since we moved the decimal 6 places to the left, the exponent of 10 is 6.

Step3: Write in scientific - notation

The scientific - notation is \(a\times10^{n}\), where \(a = 1.243\) and \(n=6\). So it is \(1.243\times 10^{6}\).

Answer:

\(1.243\times 10^{6}\)
