Notes Mathematics Form 2 - Chapter 2: Squares, Square Roots, Cubes and Cube Roots.

Squares of numbers can be either positive or negative. Usually we write positive squares without bracket and negative squares with bracket.

Square root only available for positive numbers. You can prove this by using calculator. You are going to get MATH ERROR for square root of negative numbers.

Cubes and cube roots have the same rule. It both can be either positive or negative numbers, depends on the questions. Positive cubes or cube roots give positive answers while negative cubes or cuber roots give negative answers.

I hope the following notes can make your mathematics much easier :))
