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. Some people refer to n4 as n “ tesseracted ”, “ hypercubed ”, “ zenzizenzic ...
On scientific calculators, it is usually known as "SCI" display mode. In scientific notation, nonzero numbers are written in the form. or m times ten raised to the power of n, where n is an integer, and the coefficient m is a nonzero real number (usually between 1 and 10 in absolute value, and nearly always written as a terminating decimal ).
Powers of a number with absolute value less than one tend to zero: b n → 0 as n → ∞ when | b | < 1. Any power of one is always one: b n = 1 for all n if b = 1. Powers of –1 alternate between 1 and –1 as n alternates between even and odd, and thus do not tend to any limit as n grows.
By comparison, powers of two with negative exponents are fractions: for a negative integer n, 2 n is one half multiplied by itself n times. Thus the first few powers of two where n is negative are 1 / 2, 1 / 4, 1 / 8, 1 / 16, etc. Sometimes these are called inverse powers of two because each is the multiplicative inverse of a positive power of two.
2.0–2.9 Minor I Felt slightly by some people. No damage to buildings. Over one million per year 3.0–3.9 Slight II to III Often felt by people, but very rarely causes damage. Shaking of indoor objects can be noticeable. Over 100,000 per year 4.0–4.9 Light IV to V Noticeable shaking of indoor objects and rattling noises.
Square (algebra) 5⋅5, or 52 (5 squared), can be shown graphically using a square. Each block represents one unit, 1⋅1, and the entire square represents 5⋅5, or the area of the square. In mathematics, a square is the result of multiplying a number by itself. The verb "to square" is used to denote this operation.
In mathematics, the logarithm is the inverse function to exponentiation. That means that the logarithm of a number x to the base b is the exponent to which b must be raised to produce x. For example, since 1000 = 103, the logarithm base of 1000 is 3, or log10 (1000) = 3.
Quaternary / kwəˈtɜːrnəri / is a numeral system with four as its base. It uses the digits 0, 1, 2, and 3 to represent any real number. Conversion from binary is straightforward. Four is the largest number within the subitizing range and one of two numbers that is both a square and a highly composite number (the other being thirty-six ...
