NCERT Exemplar Class 8 Maths Chapter 8: Exponents and Powers
Chapter 8 of the NCERT Exemplar Solutions for Class 8 Maths introduces students to the powerful concept of Exponents and Powers. It begins by revisiting the laws of exponents, such as:
-
aᵐ × aⁿ = aᵐ⁺ⁿ
-
aᵐ ÷ aⁿ = aᵐ⁻ⁿ
-
(aᵐ)ⁿ = aᵐⁿ
-
a⁰ = 1
These laws help simplify large and complex numerical expressions. Students practice applying these rules through NCERT solutions for Class 8 Maths, which explain each step in detail.
Another important subtopic is scientific notation, which allows extremely large or very small numbers to be written conveniently using powers of 10. This concept is highly useful in both mathematics and science. Students also explore problems involving the comparison of numbers expressed in standard form. The NCERT Exemplar Solutions for Class 8 Maths enrich learning with advanced problems where multiple laws of exponents must be applied together. These exercises sharpen calculation speed and accuracy. This chapter also develops connections with NCERT solutions for Class 8 Maths, as exponents are frequently used in scientific calculations, such as expressing the speed of light or microscopic measurements. By mastering exponents, learners build a strong base for exponential functions and logarithms in higher classes, making this chapter crucial for both academic success and real-world applications.
