Question

what coefficient should be used when writing 10490 in scientific notation? * 1 point
your answer
this is the metric base unit used to measure length * 1 point

Explanation:

Step1: Recall scientific - notation form

Scientific notation is \(a\times10^{n}\), where \(1\leqslant|a|\lt10\) and \(n\) is an integer.

Step2: Convert 10490 to scientific notation

Move the decimal point 4 places to the left: \(10490 = 1.049\times10^{4}\), so the coefficient \(a = 1.049\).

Step3: Recall metric base - unit for length

The metric base unit for length is the meter.

Answer:

1. \(1.049\)
2. Meter
