## List of Formulas in NCERT Solutions Class 8 Maths Chapter 12

There are seven exponent rules, or laws of exponents, that apply to these exponent equations, and every student needs to learn them. Memorizing these laws is also essential to achieve good marks in the class 8 maths exam. NCERT solutions class 8 maths Chapter 12 covers all the necessary laws of exponents explained with examples for students to gain an in-depth understanding. Some important formulas covered in these solutions are given below:

**Product of Powers Rule:**If multiplying two bases with the same value, write the base the same and then add the exponents to get the solution. I.e, a^{m}x a^{n}= a^{m+n}

**The Quotient of Powers Rule:**When dividing two bases of the same value, keep the base the same and subtract the exponent values. I.e., a^{m}÷ a^{n}= a^{m-n}

**Power of a Power Rule:**This rule is used to solve exponent equations where one exponent power is raised by another power. In such equations, multiply the exponents together by keeping the same base. I.e., (a^{m })^{n }= a^{mn}

**Power of a Product Rule:**When any base is being multiplied by an exponent, distribute the exponent to each part of the base. I.e., (ab)^{m}= a^{m}× b^{m}

**Power of a Quotient Rule:**This rule is about raising a quotient by a power. In this rule, the exponent needs to be distributed to all values of a quotient within the brackets. I.e., (a ÷ b)^{m}= a^{m}÷ b^{m}

**Zero Power Rule:**Any base raised to the power of zero is equal to one. I.e., a^{0}= 1

**Negative Exponent Rule:**When a number has a negative exponent, flip it into a reciprocal to turn the exponent into a positive exponent. I.e, a^{-m}= 1/a^{m}
