Introduction

In this article, we will be solving for the value of n in the function h(n) = 3, where h(n) is defined as the fourth root of 3n - 11. This problem involves algebraic manipulation and solving a quadratic equation. We will start by setting up the equation and then proceed to solve for n.

Setting Up the Equation

The function h(n) is defined as:

h(n) = √[4](3n - 11)

We are given that h(n) = 3, so we can set up the equation:

√[4](3n - 11) = 3

Eliminating the Fourth Root

To eliminate the fourth root, we can raise both sides of the equation to the power of 4:

(√[4](3n - 11))^4 = 3^4

This simplifies to:

3n - 11 = 81

Solving for n

Now we can solve for n by adding 11 to both sides of the equation:

3n = 81 + 11

3n = 92

Next, we can divide both sides of the equation by 3:

n = 92/3

Simplifying the Fraction

The fraction 92/3 can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 1. However, we can simplify it further by dividing both the numerator and the denominator by 1 and then reducing the fraction to its simplest form.

n = 92/3

Conclusion

In this article, we solved for the value of n in the function h(n) = 3, where h(n) is defined as the fourth root of 3n - 11. We started by setting up the equation and then proceeded to eliminate the fourth root by raising both sides of the equation to the power of 4. We then solved for n by adding 11 to both sides of the equation and dividing both sides by 3. The final answer is n = 92/3.

Final Answer

n = 92/3
