Introduction

Exponents are a fundamental concept in mathematics, used to represent repeated multiplication of a number. In this article, we will explore how to express equations using exponents, with a focus on the equation $2^6 = 64$ . We will delve into the world of exponents, discussing their properties, rules, and applications.

What are Exponents?

Exponents are a shorthand way of representing repeated multiplication of a number. For example, the expression $2^3$ can be read as "2 to the power of 3" or "2 cubed". This means that 2 is multiplied by itself 3 times: $2^3 = 2 \times 2 \times 2 = 8$ .

Properties of Exponents

Exponents have several properties that make them useful in mathematics. Some of the key properties of exponents include:

Product of Powers: When multiplying two numbers with the same base, we can add their exponents. For example, $2^3 \times 2^4 = 2^{3+4} = 2^7 = 128$ .
Power of a Power: When raising a power to another power, we can multiply the exponents. For example, $(2^3)^4 = 2^{3 \times 4} = 2^{12} = 4096$ .
Zero Exponent: Any number raised to the power of 0 is equal to 1. For example, $2^0 = 1$ .
Negative Exponent: A negative exponent can be rewritten as a positive exponent by taking the reciprocal of the base. For example, $2^{-3} = \frac{1}{2^3} = \frac{1}{8}$ .

Expressing Equations with Exponents

Now that we have discussed the properties of exponents, let's return to the equation $2^6 = 64$ . This equation can be expressed using exponents as:

2^6 = 2 \times 2 \times 2 \times 2 \times 2 \times 2 = 64

This equation can also be rewritten using the product of powers property:

2^6 = 2^3 \times 2^3 = 8 \times 8 = 64

Simplifying Equations with Exponents

Exponents can be used to simplify equations by combining like terms. For example, consider the equation $2^3 + 2^3 + 2^3 = 64$ . This equation can be simplified using the product of powers property:

2^3 + 2^3 + 2^3 = 3 \times 2^3 = 3 \times 8 = 24
