Answer 1

Ответ:

Пошаговое объяснение:

1) 215°−215°=0°

2) (15°+15°)2=30°*2=60°

3) 215°1−215°=0,1°

Answer 2

Let's solve each of the given expressions:

1. 215° - 215°: When you subtract the same value from itself, the result is always zero. Therefore, 215° - 215° equals 0.

2. (15° + 15°)²: First, we perform the addition inside the parentheses: 15° + 15° equals 30°. Then, we square the result: 30°² = 900°.

So, (15° + 15°)² equals 900°.

3. 215°1 - 215°: It seems there might be a typographical error in this expression since the "1" following 215° doesn't seem to have any mathematical significance. If you clarify the intent or provide more information, I'll be happy to help you further.
