The question of what 4 squared is, is a fundamental one in mathematics. To answer it, we need to understand the concept of squaring a number. Squaring a number means multiplying that number by itself. In mathematical terms, this is represented as (x^2), where (x) is the number being squared.
So, when we ask what 4 squared is, we are asking what (4^2) equals. To find the answer, we multiply 4 by itself: (4 \times 4 = 16).
Therefore, 4 squared, or (4^2), equals 16.
