Question

how do you write 3,000,000 in scientific notation? × 10

Explanation:

Step1: Move decimal point

Move the decimal - point in 3000000 to the left until there is only one non - zero digit to the left of the decimal point. We get 3.0.

Step2: Count decimal places moved

We moved the decimal point 6 places to the left.

Step3: Write in scientific notation

In scientific notation, a number is written as \(a\times10^{n}\), where \(1\leqslant|a|\lt10\) and \(n\) is an integer. So, 3000000 in scientific notation is \(3\times 10^{6}\).
