Introduction

In this article, we will delve into solving for the value of $n$ in the given equation $\frac{216^{n-2}}{\left(\frac{1}{36}\right)^{3n}}=216$ . This equation involves exponentiation and fractions, making it a challenging problem to solve. We will break down the solution step by step, using algebraic manipulations and properties of exponents to simplify the equation and isolate the variable $n$ .

Simplifying the Equation

The first step in solving the equation is to simplify the expression on the left-hand side. We can start by rewriting the fraction as a product of two terms:

\frac{216^{n-2}}{\left(\frac{1}{36}\right)^{3n}} = 216^{n-2} \cdot \left(36\right)^{3n}

Next, we can simplify the expression inside the parentheses by rewriting $36$ as $6^2$ :

216^{n-2} \cdot \left(36\right)^{3n} = 216^{n-2} \cdot \left(6^2\right)^{3n}

Using the property of exponents that states $\left(a^b\right)^c = a^{bc}$ , we can simplify the expression further:

216^{n-2} \cdot \left(6^2\right)^{3n} = 216^{n-2} \cdot 6^{6n}

Equating the Exponents

Now that we have simplified the expression, we can equate the exponents on both sides of the equation:

216^{n-2} \cdot 6^{6n} = 216

Since $216 = 6^3$ , we can rewrite the equation as:

216^{n-2} \cdot 6^{6n} = 6^3

Using the Property of Exponents

Using the property of exponents that states $a^b \cdot a^c = a^{b+c}$ , we can simplify the expression on the left-hand side:

216^{n-2} \cdot 6^{6n} = 6^{3+6n}

Equating the Exponents Again

Now that we have simplified the expression, we can equate the exponents on both sides of the equation:

6^{3+6n} = 6^3

Solving for $n$

Since the bases are the same, we can equate the exponents:

3+6n = 3

Subtracting $3$ from both sides gives us:

6n = 0

Dividing both sides by $6$ gives us:

n = 0

However, this is not the only possible solution. We can also divide both sides by $6$ and then multiply both sides by $-1$ to get:

n = -\frac{1}{3}

Conclusion

In this article, we have solved for the value of $n$ in the given equation $\frac{216^{n-2}}{\left(\frac{1}{36}\right)^{3n}}=216$ . We have broken down the solution step by step, using algebraic manipulations and properties of exponents to simplify the equation and isolate the variable $n$ . The final answer is $n = -\frac{1}{3}$ .

Final Answer

The final answer is $\boxed{-\frac{1}{3}}$ .
