What power of 10 is equal to 1,000,000?

To determine what power of 10 is equal to 1,000,000, we need to express the number in terms of its base 10 exponential form.

1,000,000 can be broken down as follows: it has six zeros. Therefore, we can represent it as 10 multiplied by itself six times, which is written in exponential form as 10 to the sixth power. This notation signifies that 10 is being raised to the power of 6.

In summary, 1,000,000 is equal to 10 raised to the sixth power, which confirms that the correct answer is found in option B. Understanding this principle is essential in aviation maintenance and mathematics, as the ability to manipulate and convert numbers in scientific notation frequently aids in simplifying calculations and presentations of large figures.
