Mathematics · Week 1
Module 1: The Real Number System
Learn how to identify rational and irrational numbers, calculate roots, and estimate where irrational numbers fall on a number line.
Learning objectives: By the end of this module, you should be able to classify real numbers, evaluate perfect-square and perfect-cube roots, estimate nonperfect roots, and explain your reasoning.
Lesson 1 · Rational and irrational numbers
A rational number can be written as a fraction a/b, where a and b are integers and b ≠ 0. Terminating and repeating decimals are rational.
An irrational number cannot be written as a ratio of two integers. Its decimal expansion does not terminate or repeat.
Worked example 1
Classify √49 and √11.
√49 = 7 = 7/1 → rational
Because 11 is not a perfect square, √11 is irrational.
The principal square root of a nonnegative number is its nonnegative square root. A cube root is a number that, when multiplied by itself three times, gives the original number.
Worked example 2
√81 = 9, because 9² = 81
∛(−125) = −5, because (−5)³ = −125
Important: √64 = 8, but the equation x² = 64 has two solutions, x = 8 and x = −8.
Lesson 3 · Approximating irrational numbers
Use neighboring perfect squares to bound a square root, then refine the estimate.
Worked example 3
Estimate √20 to one decimal place.
4² = 16 < 20 < 25 = 5²
So 4 < √20 < 5. Since 4.47² ≈ 19.98, √20 ≈ 4.5 to one decimal place.
On a number line, √20 lies between 4 and 5, slightly below 4.5.
