Answer 1

 вот ваш ответ это точно правильно

Answer 2

I can help you with math problems. The expression you entered is:

$$2\sin\frac{\pi}{4}+\sqrt{2}\cos\frac{\pi}{4}$$

To find the value of this expression, we can use the following trigonometric identities:

$$\sin\frac{\pi}{4}=\cos\frac{\pi}{4}=\frac{\sqrt{2}}{2}$$

Substituting these values into the expression, we get:

$$2\cdot\frac{\sqrt{2}}{2}+\sqrt{2}\cdot\frac{\sqrt{2}}{2}$$

Simplifying, we get:

$$\sqrt{2}+\frac{2}{2}$$

The final answer is:

$$\sqrt{2}+1$$
