Question

a megawatt wind turbine can produce about 8,000,000 watt hours of electricity each year. write 8,000,000 in scientific notation. 8,000,000 = × 10

Explanation:

Step1: Move decimal point

Move the decimal - point in 8000000 to the left until there is only one non - zero digit to the left of the decimal point. We get 8.0.

Step2: Count the number of places moved

The decimal point was moved 6 places to the left. In scientific notation, a number is written as \(a\times10^{n}\), where \(1\leqslant|a|\lt10\) and \(n\) is an integer. Here, \(a = 8\) and \(n=6\).

Answer:

\(8\times10^{6}\)
