As follows: calculate the second power of (- 2), the second power of 2, the third power of (- 2), the third power of 2 Calculate the second power of (- 2), the second power of 2, the third power of (- 2), and the third power of 2. In connection with the power of such specific numbers, do you think the following formulas hold when a < 0? 1. The square of a > 0.2. The square of a = - A 3. The square of a = - the square of a 4. The third power of a = (- a) the third power Note that 2 is not the same as 3, one is the opposite of the square of a, the other is the square of (- a)
