FAQs on Introduction to Square Roots Video Lecture - Vedic Math for Junior Classes - English - Class 1

1. What is a square root?
Ans. A square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 16 is 4, because 4 × 4 = 16.
2. How do you calculate the square root of a perfect square?
Ans. To calculate the square root of a perfect square, you can identify the number that, when multiplied by itself, equals the perfect square. For example, to find the square root of 25, you can determine that 5 × 5 = 25, so the square root of 25 is 5.
3. What is the difference between a perfect square and a non-perfect square?
Ans. A perfect square is a number that can be expressed as the square of an integer, such as 1, 4, 9, 16, and 25. A non-perfect square, on the other hand, cannot be expressed in this way; for example, the square root of 7 is not an integer and is approximately 2.65.
4. Can square roots be negative?
Ans. Square roots can be negative when considering complex numbers, but in the real number system, the square root is defined as a non-negative value. For instance, the square root of 16 is 4, not -4, even though (-4) × (-4) = 16.
5. How can square roots be simplified?
Ans. Square roots can be simplified by factoring the number into its prime factors and identifying pairs. For example, to simplify √50, you can break it down to √(25 × 2) = √25 × √2 = 5√2.
