Introduction

Solving equations with fractional exponents can be a challenging task, especially when dealing with large numbers. In this article, we will focus on finding the positive solution of the equation 6x92+2=30746x^{\frac{9}{2}} + 2 = 3074. This equation involves a fractional exponent, which requires a different approach to solve. We will use algebraic manipulations and properties of exponents to isolate the variable and find the positive solution.

Understanding the Equation

The given equation is 6x92+2=30746x^{\frac{9}{2}} + 2 = 3074. The first step is to understand the properties of fractional exponents. A fractional exponent is a way of expressing a number as a power of another number. In this case, the exponent is 92\frac{9}{2}, which means that the base xx is raised to the power of 92\frac{9}{2}. This can be rewritten as x92=(x12)9x^{\frac{9}{2}} = (x^{\frac{1}{2}})^9.

Isolating the Variable

To isolate the variable xx, we need to get rid of the constant term 22 on the left-hand side of the equation. We can do this by subtracting 22 from both sides of the equation. This gives us 6x92=30726x^{\frac{9}{2}} = 3072.

Simplifying the Equation

The next step is to simplify the equation by getting rid of the coefficient 66. We can do this by dividing both sides of the equation by 66. This gives us x92=512x^{\frac{9}{2}} = 512.

Using Properties of Exponents

Now that we have simplified the equation, we can use the properties of exponents to rewrite the equation. We know that x92=(x12)9x^{\frac{9}{2}} = (x^{\frac{1}{2}})^9. Therefore, we can rewrite the equation as (x12)9=512(x^{\frac{1}{2}})^9 = 512.

Finding the Positive Solution

To find the positive solution of the equation, we need to isolate the variable xx. We can do this by taking the ninth root of both sides of the equation. This gives us x12=8x^{\frac{1}{2}} = 8.

Squaring Both Sides

Now that we have isolated the variable x12x^{\frac{1}{2}}, we can square both sides of the equation to get rid of the fractional exponent. This gives us x=64x = 64.

Conclusion

In this article, we have found the positive solution of the equation 6x92+2=30746x^{\frac{9}{2}} + 2 = 3074. We used algebraic manipulations and properties of exponents to isolate the variable and find the positive solution. The final answer is x=64x = 64.
