Question

Quizplus · Accepted Answer

In scientific notation, we move the decimal point to the left of the first non-zero digit and multiply by 10 raised to the power of the number of places we moved. Therefore, to express 10,000,000 in scientific notation, we move the decimal point 7 places to the left of the first non-zero digit (which is 1 in this case) and get 1.0. To obtain the exponent, we count the number of places we moved the decimal point, which is 7, and write it as a power of 10, giving us 10^7. Thus, 10,000,000 in standard scientific notation is 1.0 x 10^7, which is represented by choice C.
