Summary - In a given sentence, the variables are replaced by letters and the different operations are replaced by their mathematical symbols. We now arrive at a formula. In a given sentence, the variables are replaced by letters and the different operations are replaced by their..

If m is a positive integer, a x a x a .. m times is written as am. a is called the base and m is the power. We read it as "a raised to the power m". The power is also called "the index" or "the exponent". When the power or index is a fraction say then and it is a surd of order n. In..

>Find the fraction which becomes when the denominator is increased by 5 and is equal to when the numerator is diminished by 4. Let the fraction by When y is increased by 5, fraction becomes or 2x = y + 5 2x - y = 5 (1) When x is diminished by 4, fraction..

A is called the composite function of f and g. (ii) If f and g be functions from A to A then fog and gof are both defined. In general fog gof. A function from A x A into A is called a binary operation on A..

An irrational root of a positive rational number is called a surd. Consider a number with base 'a' as a positive rational number with power of a fraction, say then Since is an n t h root, it is called a surd of order n, if it is irrational. e.g., (i) is a surd of order 3. (ii) ..

Let us refer to a circuit consisting of two switches p and q connected in parallel with a lamp and battery as shown in figure. In this case, the lamp will glow if and only if at least one of the switches is closed. In binary language we say the switch will glow if at least one of the values of p..
