Question

(1/2+2)^2+ 1/2(4+7 1/2)

Answer 1

Решение
(1/2+2)^2+ 1/2(4+7 1/2) = 2,5² + (1/2)*(11,5)² = 
= 6,25 + (1/2)*132,25 = 6,25 + 66,125 = 72,375

Answer 2

Let's break down the expression step by step:

(1/2 + 2)^2 + 1/2(4 + 7 1/2)

First, let's simplify the expression inside the parentheses:

(1/2 + 2) = 2 1/2

Next, let's calculate the square of 2 1/2:

(2 1/2)^2 = (5/2)^2 = 25/4

Now, let's simplify the expression inside the second set of parentheses:

(4 + 7 1/2) = 11 1/2

Finally, let's multiply 1/2 by 11 1/2:

1/2 * 11 1/2 = 11/2 * 1/2 = 11/4

Now, we can substitute the simplified values back into the original expression:

(1/2 + 2)^2 + 1/2(4 + 7 1/2) = (2 1/2)^2 + 1/2(11 1/2) = 25/4 + 11/4 = 36/4 = 9

Therefore, the result of the expression (1/2 + 2)^2 + 1/2(4 + 7 1/2) is 9.
