Evaluate :
` ((-5)/( 2))^(2) `

Answer

To evaluate the expression \(\left(-\frac{5}{2}\right)^{2}\), follow these steps:

### Step 1: Understand the expression
The expression \(\left(-\frac{5}{2}\right)^{2}\) means that we need to multiply \(-\frac{5}{2}\) by itself.

### Step 2: Write the multiplication
\[ \left(-\frac{5}{2}\right)^{2} = \left(-\frac{5}{2}\right) \times \left(-\frac{5}{2}\right) \]

### Step 3: Multiply the numerators
Multiply the numerators:
\[ -5 \times -5 = 25 \]

### Step 4: Multiply the denominators
Multiply the denominators:
\[ 2 \times 2 = 4 \]

### Step 5: Combine the results
Now combine the results from the numerators and denominators:
\[ \left(-\frac{5}{2}\right)^{2} = \frac{25}{4} \]

### Final Answer
Thus, the final answer is:
\[ \frac{25}{4} \]
