SUMMARY

The expression $\sqrt{5} * \left(\frac{5}{4}\right)^{\frac{1}{2}}$ simplifies correctly to $\frac{5}{2}$. The simplification process involves recognizing that $x^{1/2}$ is equivalent to $\sqrt{x}$. By applying this knowledge, the expression can be rewritten as $\frac{\sqrt{5} \cdot \sqrt{5}}{2}$, which simplifies to $\frac{5}{2}$. This conclusion is confirmed by multiple participants in the discussion.

Hint: [math]x^{1/2} = \sqrt{x}[/math]

Can you finish from here?

$5^\frac{1}{2} * \frac{5^\frac{1}{2}}{2^2\frac{1}{2}}$

$5^\frac{1}{2} * \frac{5^\frac{1}{2}}{2}$

From there ... (Thinking)
 
$$\frac{5^{1/2}\cdot5^{1/2}}{2}$$

Does that help? (See topsquark's post).

According to topsquark $\displaystyle x^{1/2} = \sqrt{x}$

$$\frac{\sqrt{5}\cdot\sqrt{5}}{2}=\frac{\sqrt{5}^2}{2}=\frac{5}{2}$$

Correct?

Many THanks :)
