Conversely, non-perfect squares yield results that are irrational numbers, meaning the decimal expansion is infinite and non-repeating. Another misconception is forgetting that every positive number has two square roots—a positive and a negative—while the principal root is always the positive one.
Square Root Basics Negative Numbers Complex Roots
Their square roots are whole numbers. For instance, √50 can be broken down into √(25 × 2).
The square root of 2 or 5 falls into this category, requiring approximation for practical use. Examples include 4 (2x2), 9 (3x3), 16 (4x4), and 25 (5x5).
