"Squared" is often written as a little 2 like this: This says "4 Squared equals 16" (the little 2 means the number appears twice in multiplying, so 4×4=16). Square Root. A square root goes the other direction:. 3 squared is 9, so a square root of 9 is 3. It is like asking:

Given a number z, the cube root of z, denoted RadicalBox[z, 3] or z^(1/3) (z to the 1/3 power), is a number a such that a^3=z. The cube root is therefore an nth root with n=3. Every real number has a unique real cube root, and every nonzero complex number has three distinct cube roots. The schoolbook definition of the cube root of a negative number is (-x)^(1/3)=-(x^(1/3)).

This MATLAB function returns the square root of each element of the array X. The sqrt function's domain includes negative and complex numbers, which can lead to unexpected results if used. Examples. collapse all. MathWorks is the leading developer of mathematical computing software for engineers and scientists.

Finally, add the interest back to the principal. numbers, both positive and negative. Imaginary Numbers: Imaginary numbers can be expressed as some real number times the square root of negative one.

For nonnegative integers n and m, the value of n m is the number of functions from a set of m elements to a set of n elements (see cardinal exponentiation).Such functions can be represented as m-tuples from an n-element set (or as m-letter words from an n-letter alphabet).Some examples for particular values of m and n are given in the following table:

Based on the concept of real numbers, a complex number is a number of the form a + bi, where a and b are real numbers and i is an indeterminate satisfying i 2 = −1.For example, 2 + 3i is a complex number. This way, a complex number is defined as a polynomial with real coefficients in the single indeterminate i, for which the relation i 2 + 1 = 0 is imposed. Based on this definition.
