Frequently Asked Questions
What are Indices?
Indices, also called exponents or powers, indicate how many times a number is multiplied by itself.
What are Surds?
Surds are irrational roots that cannot be expressed as exact rational numbers, such as √2 and √5.
What is the law of indices for multiplication?
When multiplying powers with the same base, add the exponents: a^m × a^n = a^(m+n).
What is Rationalization?
Rationalization is the process of removing surds from the denominator of a fraction.
What is a Fractional Index?
A fractional index represents a root, such as a^(1/2) = √a and a^(1/3) = ∛a.
Why are Surds and Indices important in aptitude exams?
They test algebraic manipulation, simplification skills, numerical reasoning, and mathematical problem-solving commonly required in competitive examinations.
