Class 8 Mathematics Chapter 12 – Frequently Asked Questions
What are exponents and powers?
Exponents represent repeated multiplication of a number by itself (e.g., 2³ = 2 × 2 × 2 = 8), where the exponent indicates the number of times the base is multiplied.
How are exponents used in Assam’s agriculture?
Exponents are used to express large quantities, like crop yields or storage capacities, in compact forms using scientific notation.
What are the laws of exponents?
The laws include product rule (a^m × a^n = a^(m+n)), quotient rule (a^m ÷ a^n = a^(m-n)), and power rule ((a^m)^n = a^(m×n)).
What types of questions are in Exercises 12.1 and 12.2?
Exercise 12.1 focuses on applying laws of exponents and simplifying expressions, while 12.2 includes problems on scientific notation and real-life applications.
