NCERT Solutions Class 7 Maths Chapter 13: Points to Remember

Below are some points to remember from the NCERT Solutions for Class 7 Maths chapter 13:

  • If a is a non-zero rational number and n is a natural number, then the product a×a×a×n times⋯×a is denoted by an and is read as ‘a raised to the power n’. Rational number a is called the base and natural number n is known as the exponent. Also, an is known as the exponential form of a×a×a×(n times)⋯×a.
  • For any non-zero rational number, we have a0=1 and a1=1.
  • Laws of Exponents: If a and b are non-zero rational numbers and m and n are natural numbers, then following are the laws of exponents:
  • If am×an=am+n
  • am/an=am−n
  • If (am)n=amn=(an)m
  • (a×b)n=anbn
  • If (ab)n=anbn
