simplify : (1+3)^2-10/2

Answer 1

To simplify the expression \((1+3)^2 - \frac{10}{2}\), follow these steps:

1. Calculate the inside of the parentheses: \[ 1 + 3 = 4 \]

2. Square the result: \[ (4)^2 = 16 \]

3. Calculate \(\frac{10}{2}\): \[ \frac{10}{2} = 5 \]

4. Now substitute these results back into the expression: \[ 16 - 5 \]

5. Finally, perform the subtraction: \[ 16 - 5 = 11 \]

So, the simplified expression is \( \boxed{11} \).
