In arithmetic and algebra, the fourth power of a number n is the result of multiplying four instances of n together. So: n 4 = n × n × n × n. ... 5 (in fact 0625 ...
The base 3 appears 5 times in the multiplication, because the exponent is 5. Here, 243 is the 5th power of 3, or 3 raised to the 5th power. The word "raised" is usually omitted, and sometimes "power" as well, so 3 5 can be simply read "3 to the 5th", or "3 to the 5".
In arithmetic and algebra, the fifth power or sursolid [1] of a number n is the result of multiplying five instances of n together: n 5 = n × n × n × n × n. Fifth powers are also formed by multiplying a number by its fourth power, or the square of a number by its cube. The sequence of fifth powers of integers is:
The term hyperpower [4] is a natural combination of hyper and power, which aptly describes tetration. The problem lies in the meaning of hyper with respect to the hyperoperation sequence. When considering hyperoperations, the term hyper refers to all ranks, and the term super refers to rank 4, or tetration.
The power series definition of the exponential function makes sense for square matrices (for which the function is called the matrix exponential) and more generally in any unital Banach algebra B. In this setting, e 0 = 1 , and e x is invertible with inverse e − x for any x in B .

In scientific notation, this is written 5.9724 × 10 24 kg. The Earth's circumference is approximately 40 000 000 m. [22] In scientific notation, this is 4 × 10 7 m. In engineering notation, this is written 40 × 10 6 m. In SI writing style, this may be written 40 Mm (40 megametres). An inch is defined as exactly 25.4 mm.
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. 4 is the smallest square number > 1, the smallest semiprime and composite number, and the 3rd highly composite number. [1] The number 4 is considered unlucky in many East Asian cultures.
