| complex conjugate pair | A complex conjugate pair is of the form \(a+bi, a-bi\) | ||||
| complex number | A complex number is of the form \(a+bi\), where \(a\) and \(b\) are real numbers. We call \(a\) the real part and \(b\) the imaginary part. | ||||
| complex number system | The complex number system is made up of both the real numbers and the imaginary numbers. | ||||
| imaginary unit | The imaginary unit \(i\) is the number whose square is \(–1\). \(i^2 = -1\) or \(i=\sqrt{-1}\). | ||||
| like radicals | Like radicals are radical expressions with the same index and the same radicand. | ||||
| radical equation | An equation in which a variable is in the radicand of a radical expression is called a radical equation. | ||||
| radical function | A radical function is a function that is defined by a radical expression. | ||||
| rationalizing the denominator | Rationalizing the denominator is the process of converting a fraction with a radical in the denominator to an equivalent fraction whose denominator is an integer. | ||||
| square of a number | If \(n^2=m\), then \(m\) is the square of \(n\). | ||||
| square root of a number | If \(n^2=m\), then \(n\) is a square root of \(m\). | ||||
| standard form | A complex number is in standard form when written as \(a+bi\), where \(a\), \(b\) are real numbers. |
