Question

(a+b)² при a=3,8;b=-4​

Answer 1

(3,8+(-4))² = (-0,2)² = -0,04

Ответ: -0,04

Answer 2

To calculate the value of (a+b)² when a = 3.8 and b = -4, we substitute these values into the expression:

(a + b)² = (3.8 + (-4))²

Now we simplify:

(3.8 + (-4))² = (-0.2)²

The square of -0.2 is simply 0.04:

(-0.2)² = 0.04

Therefore, (a+b)² when a = 3.8 and b = -4 is equal to 0.04.
