Understanding the Problem

When dealing with radical expressions, it's essential to understand the properties of roots and how they interact with exponents. In this case, we're given the expression $\sqrt[4]{1296 x^4}$ , and we're asked to simplify it. To start, let's break down the components of the expression.

Breaking Down the Expression

The expression $\sqrt[4]{1296 x^4}$ consists of two main parts: the number 1296 and the variable $x^4$ . The number 1296 can be expressed as a product of prime factors, which will help us simplify the expression. We can write 1296 as $2^4 \times 3^4$ . This means that 1296 is a perfect fourth power, as it can be expressed as a product of two perfect fourth powers.

Simplifying the Number Part

Now that we've broken down the number part of the expression, let's simplify it. We can rewrite the expression as $\sqrt[4]{(2^4 \times 3^4) x^4}$ . Using the property of roots that $\sqrt[n]{a^n} = a$ , we can simplify the expression further. This property states that when we take the nth root of a number that is raised to the power of n, the result is the number itself.

Applying the Property of Roots

Applying the property of roots to our expression, we get $\sqrt[4]{(2^4 \times 3^4) x^4} = 2 \times 3 \times x = 6x$ . This simplification is possible because the number 1296 is a perfect fourth power, and the variable $x^4$ is also raised to the power of 4.

Final Simplification

The final simplified expression is $6x$ . This is the result of applying the property of roots to the original expression $\sqrt[4]{1296 x^4}$ .

Conclusion

In this article, we simplified the expression $\sqrt[4]{1296 x^4}$ by breaking down the number part and applying the property of roots. We showed that the number 1296 is a perfect fourth power and that the variable $x^4$ is also raised to the power of 4. By applying the property of roots, we were able to simplify the expression to $6x$ .
