**What is the Square Root of $$r^{64}$$?**

Understanding the Concept of Square Root

The square root of a number is a value that, when multiplied by itself, gives the original number. In mathematical terms, if we have a number 'x', then its square root is denoted by √x and is a value that satisfies the equation x = (√x)^2.

Applying the Concept to $$r^{64}$$

Now, let's apply this concept to the given expression $$r^{64}$$. We need to find the square root of this expression, which means we need to find a value that, when multiplied by itself, gives $$r^{64}$$.

Using the Properties of Exponents

To simplify this expression, we can use the properties of exponents. Specifically, we can use the property that states: (a^m)n = a^(m*n), where 'a' is a number and 'm' and 'n' are exponents.

Simplifying the Expression

Using this property, we can rewrite $$r^{64}$$ as (r³²⁾2. This is because 64 = 32*2, so we can rewrite the expression as (r³²⁾2.

Finding the Square Root

Now, we can find the square root of this expression by taking the square root of both the inner and outer expressions. This gives us: √(r³²⁾2 = √(r^32) * √(r^32) = r^16.

Conclusion

Therefore, the square root of $$r^{64}$$ is $$r^{16}$$.
