Understanding Higher Roots

When dealing with higher roots, such as the 7th root, it's essential to understand the properties of exponents and radicals. The nth root of a number can be expressed as the number raised to the power of 1/n. In this case, we're dealing with the 7th root of $a^{35}$ .

Breaking Down the Expression

To simplify the expression $\sqrt[7]{a^{35}}$ , we need to break it down and understand the properties of exponents. We can start by expressing the 7th root as a fractional exponent:

\sqrt[7]{a^{35}} = a^{\frac{35}{7}}

Simplifying the Fractional Exponent

Now that we have the expression in fractional exponent form, we can simplify it further. We can divide the numerator and denominator by their greatest common divisor (GCD), which is 7:

a^{\frac{35}{7}} = a^5

Understanding the Result

The simplified expression is $a^5$ . This means that the 7th root of $a^{35}$ is equal to $a^5$ . This is because the 7th root of a number can be expressed as the number raised to the power of 1/7, and in this case, the exponent 35 can be divided by 7 to get 5.

Real-World Applications

Higher roots have many real-world applications, such as in physics, engineering, and computer science. For example, in physics, the 7th root of a number can be used to calculate the power of a wave or the frequency of a signal. In engineering, higher roots can be used to design and optimize systems, such as electrical circuits or mechanical systems.

Conclusion

In conclusion, simplifying the expression $\sqrt[7]{a^{35}}$ involves breaking it down and understanding the properties of exponents and radicals. By expressing the 7th root as a fractional exponent and simplifying it further, we arrive at the final result of $a^5$ . This demonstrates the importance of understanding higher roots and their applications in various fields.
