How to Solve Exponents Equations in Class 6 Maths?
FAQs on Exponents Equations Practice Worksheet for Class 6 Maths
1. How do you solve exponents in 6th grade?
To solve exponents in 6th grade, you must understand the base and the exponent, and then apply the correct laws of exponents to simplify the expression. The key is to break down the problem into smaller, manageable steps.
- Identify the Base and Exponent: The base is the number being multiplied, and the exponent (or power) tells you how many times to multiply the base by itself. For example, in 5³, 5 is the base and 3 is the exponent.
- Expand the Expression: Write out the multiplication. For 5³, this would be 5 × 5 × 5.
- Calculate the Value: Perform the multiplication to find the final value (5 × 5 × 5 = 125).
- Apply Laws of Exponents: For more complex equations with exponents, use the product, quotient, and zero exponent laws to simplify before calculating.
2. What are the main laws of exponents for Class 6?
The main laws of exponents for Class 6 provide rules for simplifying expressions involving powers and bases. These foundational rules make solving complex exponent equations much easier.
- Product of Powers Law: When multiplying two powers with the same base, you add the exponents (e.g., aᵐ × aⁿ = aᵐ⁺ⁿ).
- Quotient of Powers Law: When dividing two powers with the same base, you subtract the exponents (e.g., aᵐ ÷ aⁿ = aᵐ⁻ⁿ).
- Power of a Power Law: To find the power of a power, you multiply the exponents (e.g., (aᵐ)ⁿ = aᵐⁿ).
- Zero Exponent Law: Any non-zero number raised to the power of zero is 1 (e.g., a⁰ = 1).
3. What is an exponent equation?
An exponent equation is a mathematical statement where the variable you need to solve for appears in the exponent. These equations require using the properties of exponents to find the value of the unknown.
For example, in the equation 2ˣ = 8, you need to find the value of 'x'. Since 8 can be written as 2³, the equation becomes 2ˣ = 2³. Therefore, x = 3. This Class 6 maths worksheet provides practice on solving such equations.

5. What are the formulas for exponents and powers in Class 6?
The key formulas for exponents and powers in Class 6 are based on the fundamental laws of exponents. These formulas are used to simplify expressions and solve equations involving exponents.
- Product Rule: aᵐ × aⁿ = aᵐ⁺ⁿ
- Quotient Rule: aᵐ / aⁿ = aᵐ⁻ⁿ
- Power of a Power Rule: (aᵐ)ⁿ = aᵐⁿ
- Power of a Product Rule: (ab)ⁿ = aⁿbⁿ
- Zero Exponent Rule: a⁰ = 1 (for a ≠ 0)
- Negative Exponent Rule: a⁻ⁿ = 1/aⁿ

10. What is the difference between a base and an exponent?
In an exponential expression, the base and the exponent are two distinct parts with different functions. Understanding this difference is fundamental to learning about exponents and powers.
- The base is the number that is to be multiplied by itself. It is the larger number written on the line.
- The exponent (also called the power or index) is the small number written as a superscript. It indicates how many times the base is to be multiplied.
- For example, in 7⁴, the number 7 is the base and the number 4 is the exponent. This means you must multiply 7 by itself 4 times: 7 × 7 × 7 × 7.
