Introduction

Simplifying algebraic expressions is a crucial skill in mathematics, and it requires a deep understanding of the underlying concepts. In this article, we will focus on simplifying a complex expression involving exponents and fractions. The given expression is 4nβˆ’1Γ—8n+1Γ—1232n\frac{4^{n-1} \times 8^{n+1} \times \frac{1}{2}}{32^n}, and our goal is to simplify it to its simplest form.

Understanding Exponents and Fractions

Before we dive into simplifying the expression, let's review some basic concepts related to exponents and fractions. Exponents are a shorthand way of representing repeated multiplication. For example, aba^b means aa multiplied by itself bb times. On the other hand, fractions are a way of representing a part of a whole. In this expression, we have a fraction with a numerator and a denominator.

Simplifying the Expression

To simplify the expression, we need to apply the rules of exponents and fractions. Let's start by simplifying the numerator. We can rewrite 8n+18^{n+1} as (23)n+1(2^3)^{n+1}, which is equal to 23(n+1)2^{3(n+1)}. Similarly, we can rewrite 4nβˆ’14^{n-1} as (22)nβˆ’1(2^2)^{n-1}, which is equal to 22(nβˆ’1)2^{2(n-1)}. Now, we can substitute these expressions back into the original expression.

Applying the Rules of Exponents

Now that we have simplified the numerator, let's apply the rules of exponents to simplify the expression further. We can start by combining the exponents in the numerator using the rule abΓ—ac=ab+ca^b \times a^c = a^{b+c}. This gives us 22(nβˆ’1)Γ—23(n+1)Γ—122^{2(n-1)} \times 2^{3(n+1)} \times \frac{1}{2}. Next, we can simplify the fraction by multiplying the numerator and denominator by the reciprocal of the denominator.

Simplifying the Fraction

To simplify the fraction, we need to multiply the numerator and denominator by the reciprocal of the denominator. The reciprocal of 12\frac{1}{2} is 22, so we can multiply the numerator and denominator by 22. This gives us 22(nβˆ’1)Γ—23(n+1)Γ—22^{2(n-1)} \times 2^{3(n+1)} \times 2.

Applying the Product of Powers Rule

Now that we have simplified the fraction, let's apply the product of powers rule to simplify the expression further. The product of powers rule states that abΓ—ac=ab+ca^b \times a^c = a^{b+c}. We can apply this rule to the expression 22(nβˆ’1)Γ—23(n+1)Γ—22^{2(n-1)} \times 2^{3(n+1)} \times 2.

Simplifying the Expression Further

Using the product of powers rule, we can simplify the expression as follows:

22(nβˆ’1)Γ—23(n+1)Γ—2=22(nβˆ’1)+3(n+1)+12^{2(n-1)} \times 2^{3(n+1)} \times 2 = 2^{2(n-1) + 3(n+1) + 1}

Evaluating the Exponent

Now that we have simplified the expression, let's evaluate the exponent. We can start by simplifying the expression inside the exponent.

2(nβˆ’1)+3(n+1)+1=2nβˆ’2+3n+3+12(n-1) + 3(n+1) + 1 = 2n - 2 + 3n + 3 + 1

Combining Like Terms

Next, we can combine like terms in the expression.

2nβˆ’2+3n+3+1=5n+22n - 2 + 3n + 3 + 1 = 5n + 2

Simplifying the Expression

Now that we have evaluated the exponent, let's simplify the expression further. We can rewrite the expression as 25n+22^{5n+2}.

Simplifying the Denominator

Now that we have simplified the numerator, let's simplify the denominator. We can rewrite 32n32^n as (25)n(2^5)^n, which is equal to 25n2^{5n}.

Simplifying the Expression

Now that we have simplified the numerator and denominator, let's simplify the expression further. We can rewrite the expression as 25n+225n\frac{2^{5n+2}}{2^{5n}}.

Applying the Quotient of Powers Rule

Now that we have simplified the expression, let's apply the quotient of powers rule to simplify it further. The quotient of powers rule states that abac=abβˆ’c\frac{a^b}{a^c} = a^{b-c}. We can apply this rule to the expression 25n+225n\frac{2^{5n+2}}{2^{5n}}.

Simplifying the Expression Further

Using the quotient of powers rule, we can simplify the expression as follows:

25n+225n=2(5n+2)βˆ’5n\frac{2^{5n+2}}{2^{5n}} = 2^{(5n+2)-5n}

Evaluating the Exponent

Now that we have simplified the expression, let's evaluate the exponent. We can start by simplifying the expression inside the exponent.

(5n+2)βˆ’5n=2(5n+2)-5n = 2

Simplifying the Expression

Now that we have evaluated the exponent, let's simplify the expression further. We can rewrite the expression as 222^2.
