### Rationalize Denominator

Rationalizing the denominator of a fraction word "mathematics" comes from the Greek "mathematic" which means "knowledge", "science." It derived from the adjective "Mathematik," meaning "on science." The Greek word was taken over by Latin, in the form of "mathematics", a term inherited most modern languages. Mathematics is the oldest science, a history stretching over several millennia and in several geographic areas simultaneously in the Far East to Central America, and Asia Minor and Africa to Europe. Rightly, most researchers of the evolution of culture and civilization believes that preceded the writing math, considering notches discovery of bones dating back over 20 000 years BC Geologist Belgian Jean de Heinlein of Bra court, in 1950, found in volcanic ash on the shore of a lake in Great Rift Valley of Africa, on the border between Congo and Uganda, which later was called "bone / stick Ishan go" more exactly two bones around 10-14 centimetres, with multiple incisions and a piece of quartz fixed in the thinnest end of one of the two bones. Notches, not random, are indicative of counting systems, base 10, and some elementary arithmetic.

Rationalizing the denominator is essential when involved in a fraction calculation can not be used in those calculations because the denominator contains a real number with radical (e.g., in this case, we could not bring the same common denominator fraction). To resolve this situation, recourse to rationalize the denominator of that fraction, thus eliminating radical in the denominator. A rationalize the denominator of fractions that contain radical means to turn fraction by amplifications or simplifications in order to obtain a fraction that does not contain radicals in the denominator. If fraction EF is amplified with C, we obtain EC = E F FC .If E EC contains radicals and contain no radical C expression is called conjugated

What it means to rationalize the denominator of a fraction? Rationalizing the denominator of a fraction refers to amplification with the radical fraction of the denominator. #Care is rationalized? The goal is to eliminate radical rationalization of the denominator of the fraction. To understand the better method, I will take the following examples:

ATTENTION: 1. When rationalize, multiply the numerator and denominator of the fraction. 2. When we denominator to the radical a natural number, as part (b), only amplified with the radical fraction. #La Us useful rationalization? Rationalizing the denominator of a fraction is useful to us radically different calculations.

To retain:
1.    Rationalizing the denominator of a fraction refers to amplification with the radical fraction of the denominator.
2. The goal is to eliminate radical rationalization of the denominator of the fraction.
3. When rationalize, multiply the numerator and denominator of the fraction
4. When we denominator to the radical a natural number, only the radical fraction is amplified.
5. Rationalizing the denominator of a fraction is useful to us radically different calculations.
