## FAQs on What are the various Laws of Exponents? Video Lecture - Mathematics (Maths) Class 7

 1. What is the law of exponents for multiplication?
Ans. The law of exponents for multiplication states that when multiplying two numbers with the same base, you can add their exponents. For example, if you have x^2 * x^3, you can add the exponents and write it as x^(2+3) = x^5.
 2. What is the law of exponents for division?
Ans. The law of exponents for division states that when dividing two numbers with the same base, you can subtract their exponents. For example, if you have x^7 / x^4, you can subtract the exponents and write it as x^(7-4) = x^3.
 3. What is the law of exponents for raising a power to another power?
Ans. The law of exponents for raising a power to another power states that when you have a power raised to another power, you can multiply the exponents. For example, if you have (x^2)^3, you can multiply the exponents and write it as x^(2*3) = x^6.
 4. What is the law of exponents for a negative exponent?
Ans. The law of exponents for a negative exponent states that when you have a negative exponent, you can rewrite it as the reciprocal of the positive exponent. For example, if you have x^-3, you can rewrite it as 1/x^3.
 5. What is the law of exponents for a zero exponent?
Ans. The law of exponents for a zero exponent states that any number (except zero) raised to the power of zero equals 1. For example, if you have x^0, it is equal to 1.
