# Roots Reciprocal and Surds

## Rationalization of surds

You can only add or subtract Surds in the same basic form. Sometimes if the surds are not in the same basic form and needed to be simplified and brought to the same basic form before the addition or subtraction will be carried out. Note:√a + √a = 2√a2√b – 3√b = – √b √a […]

## Operations with Surds

Operations with Surds Whenever they talk about Surds, just bear it in mind they are directly talking about irrational numbers which can not be expressed as fraction. The reason why Surds are irrational numbers is because their exact values can not be determined. The square root of all non perfect squares are irrational, π and

## Reciprocals of Numbers

The Reciprocal of any given number “x” is 1(one) all over that particular given number “x” = 1/x. (Reciprocals of Numbers) When two numerals multiply themselves and the product is 1, the two numerals are said to be reciprocals of each other. If a numeral is represented with the letter N, and N is not

## How to find Squares of any numerals without using calculator: squares of numbers

The squares of numbers are gotten when the number is multiplied by itself. When T is multiplied by T, that is T x T, it is being written as T² in a short form. Some examples of Squares are: 0.3² = 0.3 x 0.3 = 0.092.5² = 2.5 x 2.5 = 6.257² = 7 x
