In arithmetic and algebra, the fourth power of a number n is the result of multiplying four instances of n together. So: n4 = n × n × n × n. Fourth powers are also formed by multiplying a number by its cube. Furthermore, they are squares of squares.

When the exponent is \(2\), the result is called a square. When the exponent is \(3\), the result is called a cube. Memorize the squares of the integers up to \(15\) and the cubes of the integers up to \(10\). They will be used often as you progress in your study of algebra.
There are two specially-named powers: "to the second power" is generally pronounced as "squared", and "to the third power" is generally pronounced as "cubed". So "5 3" is commonly pronounced as "five cubed". When we deal with numbers, we usually just simplify; we'd rather deal with "27" than with "3 3".
Squares. The square of a number is that number times itself. 5 squared, denoted 52, is equal to 5×5, or 25. 2 squared is 22 = 2×2 = 4. One way to remember the term "square" is that there are two dimensions in a square (height and width) and the number being squared appears twice in the calculation.
4 Ιουν 2023 · For example, 3 is a square root of 9 since \(3^2 = 9\). Likewise, − 4 is a square root of 16 since \((−4)^2 = 16\). In a sense, taking a square root is the “opposite” of squaring, so the definition of square root must be intimately connected with the graph of \(y = x^2\), the squaring function.
