Introduction

Solving equations is a fundamental concept in mathematics, and it is essential to understand how to approach and solve various types of equations. In this article, we will focus on solving the equation (4x4)2=1\left(4 x^4\right)^2=1. This equation involves exponentiation and can be solved using various mathematical techniques.

Understanding the Equation

The given equation is (4x4)2=1\left(4 x^4\right)^2=1. To solve this equation, we need to understand the properties of exponents and how to manipulate them. The equation involves a squared term, which means we need to find the value of xx that satisfies the equation.

Step 1: Simplify the Equation

To simplify the equation, we can start by expanding the squared term using the power rule of exponents. The power rule states that (am)n=amn(a^m)^n = a^{mn}. Applying this rule to the given equation, we get:

(4x4)2=42β‹…(x4)2=16β‹…x8\left(4 x^4\right)^2 = 4^2 \cdot (x^4)^2 = 16 \cdot x^8

Step 2: Set Up the Equation

Now that we have simplified the equation, we can set it up as an equation:

16β‹…x8=116 \cdot x^8 = 1

Step 3: Solve for xx

To solve for xx, we can start by dividing both sides of the equation by 16:

x8=116x^8 = \frac{1}{16}

Step 4: Take the Eighth Root

To find the value of xx, we can take the eighth root of both sides of the equation:

x=1168x = \sqrt[8]{\frac{1}{16}}

Step 5: Simplify the Expression

To simplify the expression, we can rewrite 116\frac{1}{16} as 124\frac{1}{2^4}:

x=1248x = \sqrt[8]{\frac{1}{2^4}}

Step 6: Apply the Power Rule

Using the power rule, we can rewrite the expression as:

x=1248x = \frac{1}{2^{\frac{4}{8}}}

Step 7: Simplify the Fraction

To simplify the fraction, we can rewrite 48\frac{4}{8} as 12\frac{1}{2}:

x=1212x = \frac{1}{2^{\frac{1}{2}}}

Step 8: Evaluate the Expression

To evaluate the expression, we can rewrite 2122^{\frac{1}{2}} as 2\sqrt{2}:

x=12x = \frac{1}{\sqrt{2}}

Step 9: Rationalize the Denominator

To rationalize the denominator, we can multiply both the numerator and denominator by 2\sqrt{2}:

x=12β‹…22=22x = \frac{1}{\sqrt{2}} \cdot \frac{\sqrt{2}}{\sqrt{2}} = \frac{\sqrt{2}}{2}

Conclusion

In this article, we solved the equation (4x4)2=1\left(4 x^4\right)^2=1 using various mathematical techniques. We started by simplifying the equation, setting it up as an equation, solving for xx, taking the eighth root, simplifying the expression, applying the power rule, simplifying the fraction, evaluating the expression, and rationalizing the denominator. The final solution is x=22x = \frac{\sqrt{2}}{2}.
