3 hoch 4 = 3 * 3 * 3 * 3 = 81
-3 hoch 4 = - 3 * 3 * 3 * 3 = -81
(-3) hoch 4 = (-3) * (-3) * (-3) * (-3) = 81
(-3) hoch -4 = (-1/3)^4 = (-1/3) * (-1/3) * (-1/3) * (-1/3) = 1/81
-3 hoch -4 = - (1/3)^4 = - (1/3) * (1/3) * (1/3) * (1/3) = - 1/81
Siehst du selber wie man es rechnet und wo die kleinen Unterschiede sind.
