ICSE Class 8 Maths Selina Solutions Chapter 3:
Different techniques of computing the square roots of numbers are explained in Class 8 Maths, Chapter 3, "Square and Square Roots." Students must have a basic understanding of squares before moving on to learning about square roots. All it takes to find the square of any number is to multiply it by itself.
For instance: Three is the square root of nine since nine is obtained by multiplying three by itself. The squares of whole numbers, like 1, 4, 9, 16, etc., are the perfect squares. Positive numbers have two square roots to find the square roots of; a positive square root (referred to as the principal square root) and a negative square root.
To do well on the yearly exam, Class 8 ICSE students should practice problems from the Selina textbook. Students can evaluate their errors and weak points and double-check their answers with the aid of the ICSE Class 8 Maths Selina Solutions PDF. However, they must have a firm grasp of the concept of "Square and Square Roots" before they can begin answering the questions.
