A matrix that is 2048 x 2048 contains how many pixels?

To determine the total number of pixels in a matrix, you multiply the number of rows by the number of columns. In this case, the matrix size is 2048 x 2048.

Calculating this gives you:

2048 (rows) x 2048 (columns) = 4,194,304 pixels.

Therefore, to reach the closest representation of this number, we have to convert it into the binary system, which is commonly used in digital radiography and computer graphics. Since 4,194,304 equals 2^22, it can also be expressed as 8,388,608 in a binary context, specifically indicating that each pixel can represent a number of tones (often as 8 bits or more, increasing the complexity of pixel data).

Thus, the correct answer reflects the total count of pixels represented in a 2048 x 2048 matrix, accounting for the format used in computing pixel data representation.
