FAQs on What are Surds ? Video Lecture - Quantitative Aptitude for SSC CGL

1. What are surds?
Ans. Surds are numbers that cannot be expressed as a simple fraction and have an irrational square root. They are typically written in the form of √n, where n is a positive integer that is not a perfect square.
2. How do you simplify surds?
Ans. To simplify a surd, you need to express it in its simplest form by removing any perfect square factors from the radicand. For example, the surd √12 can be simplified as √(4 × 3) = 2√3.
3. What is the difference between a surd and a radical?
Ans. A surd is a number that cannot be expressed as a simple fraction and has an irrational square root. On the other hand, a radical is the symbol used to represent the square root (√) or any other root (∛, ∜) of a number.
4. How are surds used in mathematics?
Ans. Surds are used in various branches of mathematics, including algebra, geometry, and calculus. They are often encountered when dealing with irrational numbers, quadratic equations, and geometric shapes that have irrational side lengths or areas.
5. Can surds be rational numbers?
Ans. No, surds cannot be rational numbers because they cannot be expressed as a simple fraction. Rational numbers can be written as the ratio of two integers, whereas surds have an irrational square root and cannot be expressed in this form.
