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
*a*^{0}=1 and*a*^{1}=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 a
^{m}×a^{n}=a^{m+n} - a
^{m}/a^{n}=a^{m−n} - If (a
^{m})^{n}=a^{mn}=(a^{n})^{m} - (a×b)
^{n}=a^{n}b^{n} - If (ab)
^{n}=a^{n}b^{n}
