What multiples of 8 are perfect squares?

Multiples of 8 are numbers that can be expressed as 8n, where n is an integer. Perfect squares are numbers that are the result of multiplying an integer by itself, such as 1, 4, 9, 16, etc. To find which multiples of 8 are perfect squares, we need to find the numbers that can be expressed as 8n = m^2, where m is an integer.
