Study Notes
Laws of Exponents
Exponents and powers are fundamental concepts in mathematics that are used to represent repeated multiplication. They simplify the process of multiplying or dividing the same number or expression multiple times. Here, we will discuss the laws of exponents that help in simplifying expressions with exponents.
Product with Same Bases
If the base of two expressions is the same, you can add their exponents to simplify the expression. For example, if you have a m and a n, where a is the base, you can add m and n to get a (m + n). This is known as the Power of a Power Rule.
Quotient with Same Bases
If the base of two expressions is the same, you can subtract the exponents to simplify the expression. For example, if you have a m and a n, where a is the base, you can subtract m from n to get a (n - m). This is known as the Quotient Power Rule.
Product to a Power
When raising a product to a power, you distribute the power to each factor. For example, if you have a b and you want to raise it to the power of c, you can write it as (a b) c. This is known as the Product of Powers Rule.
Quotient to a Power
When raising a fraction to a power, you distribute the power to each factor in the numerator and denominator of the fraction. For example, if you have a/b and you want to raise it to the power of c, you can write it as (a b) c. This is known as the Quotient of Powers Rule.
Zero Power
Any number raised to the zero power is always equal to 1. This is known as the Zero Power Rule. For example, a 0 = 1, where a is any non-zero number.
Negative Power
A negative exponent signifies division. For example, a -m is equivalent to 1/a m, where a is the base and m is the exponent. This is known as the Negative Exponents Rule.
Quotient with Negative Power
If you have a quotient with a negative power, you take the reciprocal of the base. For example, a/b -m is equivalent to b/a m. This is known as the Negative Exponents for Quotients Rule.
Power of a Product with Different Bases
If you have two expressions with different bases and you want to raise their product to a power, you multiply the powers of the factors. For example, if you have a m and b n and you want to raise their product to the power of c, you can write it as (a b) (m + n). This is known as the Power of a Product Rule.
These laws of exponents are used to simplify expressions and make calculations easier. By understanding these rules, you can manipulate expressions with exponents more effectively.
