Introduction to Exponents and Powers

Exponents and powers are fundamental concepts in mathematics that help us simplify complex expressions and solve equations. In this article, we will focus on simplifying the given expression using exponent rules and properties. Understanding exponents and powers is crucial in mathematics, as it enables us to manipulate expressions and equations with ease.

The Given Expression

The given expression is $$2^{\frac{1}{2}} \times\left(4^2\right){-\frac{1}{2}}$$. This expression involves exponents and powers, and we need to simplify it using the rules of exponents. Simplifying expressions with exponents is a critical skill in mathematics, as it helps us solve problems and equations efficiently.

Simplifying the Expression

To simplify the given expression, we need to apply the rules of exponents. The first step is to simplify the term $$\left(4^2\right){-\frac{1}{2}}$$. Using the property of exponents that states $$(a^m)n = a^{mn}$$, we can rewrite the term as $$4^{2 \times -\frac{1}{2}} = 4^{-1}$$.

Applying the Rule of Negative Exponents

Now that we have simplified the term $$\left(4^2\right){-\frac{1}{2}}$$ to $$4^{-1}$$, we can apply the rule of negative exponents. The rule states that $$a^{-n} = \frac{1}{a^n}$$. Therefore, we can rewrite the term $$4^{-1}$$ as $$\frac{1}{4^1} = \frac{1}{4}$$.

Simplifying the Expression Further

Now that we have simplified the term $$\left(4^2\right){-\frac{1}{2}}$$ to $$\frac{1}{4}$$, we can simplify the entire expression. We can rewrite the expression as $$2^{\frac{1}{2}} \times \frac{1}{4}$$. Using the property of exponents that states $$a^m \times a^n = a^{m+n}$$, we can rewrite the expression as $$2^{\frac{1}{2} + -1} = 2^{-\frac{1}{2}}$$.

Simplifying the Final Expression

Now that we have simplified the expression to $$2^{-\frac{1}{2}}$$, we can simplify it further. Using the rule of negative exponents, we can rewrite the expression as $$\frac{1}{2^{\frac{1}{2}}}$$.

Conclusion

In this article, we simplified the expression $$2^{\frac{1}{2}} \times\left(4^2\right){-\frac{1}{2}}$$ using the rules of exponents. We applied the property of exponents that states $$(a^m)n = a^{mn}$$ to simplify the term $$\left(4^2\right){-\frac{1}{2}}$$ to $$4^{-1}$$. We then applied the rule of negative exponents to rewrite the term $$4^{-1}$$ as $$\frac{1}{4}$$. Finally, we simplified the entire expression to $$\frac{1}{2^{\frac{1}{2}}}$$.

Final Answer

The final answer to the expression $$2^{\frac{1}{2}} \times\left(4^2\right){-\frac{1}{2}}$$ is $$\frac{1}{2^{\frac{1}{2}}}$$.
