| 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.
