How to multiply a whole number by a power of 10?

To multiply a whole number by a power of 10, add as many zeros to the end of the number as the exponent in the power of 10.

For example:
567 x 10³ = 567,000 (add 3 zeros to the end of 567)
89 x 10⁴ = 890,000 (add 4 zeros to the end of 89)

In general, to multiply a whole number by 10ⁿ, where n is a positive integer, we add n zeros to the end of the number.

This method is straightforward and efficient, especially for mental math or quick calculations. Understanding the concept of place value is crucial to seeing why this method works: multiplying by powers of 10 effectively shifts the digits to the left, increasing the value of the number by the specified factor.
