FAQs on Textbook: Exponents - Mathematics for Grade 10

1. What are exponents and how are they used in mathematics?
Ans. Exponents are a way to represent repeated multiplication of a number by itself. For instance, 3 raised to the power of 2 (written as 3^2) means 3 multiplied by itself, which equals 9. In mathematics, exponents are used to simplify expressions and perform calculations involving large numbers more easily.
2. How do you multiply numbers with exponents?
Ans. To multiply numbers with the same base, you add their exponents. For example, 2^3 multiplied by 2^4 can be calculated as 2^(3+4), which is 2^7. If the bases are different, you simply calculate each exponent separately and then multiply the results.
3. What is the difference between positive and negative exponents?
Ans. A positive exponent indicates how many times to multiply the base by itself, while a negative exponent indicates how many times to divide 1 by the base. For example, 2^3 equals 8, while 2^(-3) equals 1/(2^3) or 1/8.
4. Can you explain the zero exponent rule?
Ans. The zero exponent rule states that any non-zero number raised to the power of zero equals 1. For example, 5^0 equals 1. This rule is important in simplifying expressions and understanding the behavior of exponents.
5. How do you simplify expressions that involve multiple exponents?
Ans. To simplify expressions with multiple exponents, use the laws of exponents, such as the product of powers, quotient of powers, and power of a power rules. For example, to simplify (x^2)^3, you multiply the exponents to get x^(2*3) = x^6.
