FAQs on 4 Days Timetable: Number System - Mathematics (Maths) Class 9

1. What are irrational numbers and how do they differ from rational numbers?
Ans. Irrational numbers are numbers that cannot be expressed as a fraction of two integers. This means they cannot be written in the form a/b, where a and b are integers and b is not zero. Examples of irrational numbers include the square root of 2 and pi (π). In contrast, rational numbers can be expressed as a fraction, such as 1/2 or -3/4.
2. How do real numbers encompass both rational and irrational numbers?
Ans. Real numbers include all the numbers on the number line, which consists of both rational and irrational numbers. Rational numbers are those that can be represented as fractions, while irrational numbers cannot be represented in this way. Together, they form the complete set of real numbers, which can be represented in decimal form, either terminating or non-terminating.
3. What are the basic operations that can be performed on real numbers?
Ans. The basic operations that can be performed on real numbers include addition, subtraction, multiplication, and division. Each of these operations follows specific rules and properties that apply to both rational and irrational numbers. For example, adding two real numbers will always yield another real number.
4. What are the laws of exponents and how do they apply to real numbers?
Ans. The laws of exponents are rules that describe how to handle mathematical operations involving powers. Key laws include the product of powers (a^m * a^n = a^(m+n)), the quotient of powers (a^m / a^n = a^(m-n)), and the power of a power ( (a^m)^n = a^(m*n)). These laws apply to real numbers and help simplify expressions involving exponents.
5. Why is it important to understand the number system in mathematics?
Ans. Understanding the number system is crucial in mathematics as it forms the foundation for all mathematical concepts. It helps in classifying numbers, performing operations, and solving equations. A strong grasp of the number system enhances problem-solving skills and provides a framework for advanced mathematical studies.
