Rewrite The Expression In The Form $z N$.$\frac{1}{z {-\frac{1}{2}}} = \square$

$$

Understanding the Problem

The given expression is $\frac{1}{z^{-\frac{1}{2}}}$. We are asked to rewrite this expression in the form $z^n$, where $n$ is a real number. To do this, we need to apply the rules of exponents and simplify the expression.

Applying the Rules of Exponents

The given expression can be rewritten using the rule $\frac{1}{a^n} = a^{-n}$. Applying this rule to the given expression, we get:

$$\frac{1}{z^{-\frac{1}{2}}} = z^{\frac{1}{2}}$$

Simplifying the Expression

Now that we have rewritten the expression in the form $z^n$, we can simplify it further. The expression $z^{\frac{1}{2}}$ can be rewritten as $\sqrt{z}$.

Rewriting the Expression in the Form $z^n$

Therefore, the given expression $\frac{1}{z^{-\frac{1}{2}}}$ can be rewritten in the form $z^n$ as:

$$\frac{1}{z^{-\frac{1}{2}}} = z^{\frac{1}{2}} = \boxed{\sqrt{z}}$$

Understanding the Concept of Exponents

The concept of exponents is a fundamental concept in mathematics. It allows us to represent repeated multiplication of a number by itself. For example, $a^3$ represents $a \times a \times a$. The exponent $3$ indicates that the number $a$ is multiplied by itself $3$ times.

Applying the Concept of Exponents to the Given Expression

In the given expression $\frac{1}{z^{-\frac{1}{2}}}$, the exponent $-\frac{1}{2}$ indicates that the number $z$ is multiplied by itself $-\frac{1}{2}$ times. To rewrite this expression in the form $z^n$, we need to apply the rule $\frac{1}{a^n} = a^{-n}$.

Simplifying the Expression Using the Concept of Exponents

Using the concept of exponents, we can simplify the expression $z^{-\frac{1}{2}}$ as follows:

$$z^{-\frac{1}{2}} = \frac{1}{z^{\frac{1}{2}}}$$

Rewriting the Expression in the Form $z^n$

Now that we have simplified the expression using the concept of exponents, we can rewrite the given expression $\frac{1}{z^{-\frac{1}{2}}}$ in the form $z^n$ as:

$$\frac{1}{z^{-\frac{1}{2}}} = z^{\frac{1}{2}} = \boxed{\sqrt{z}}$$

Conclusion

In conclusion, the given expression $\frac{1}{z^{-\frac{1}{2}}}$ can be rewritten in the form $z^n$ as $z^{\frac{1}{2}} = \sqrt{z}$. This demonstrates the importance of understanding the concept of exponents and applying the rules of exponents to simplify expressions.
