Cómo resolver potencias de números enteros BASE NEGATIVA
Si el EXPONENTE es PAR, el resultado es un número entero POSITIVO
(−3)4=(+9)×(+9)=81
3
Cómo resolver potencias de números enteros BASE NEGATIVA
Si el EXPONENTE es IMPAR, el resultado es un número entero NEGATIVO
(−3)3=(+9)×(−3)=−27
4
Y RECUERDA: SI LA BASE ES POSITIVA EL RESULTADO SIEMPRE SERÁ POSITIVO
(3)3=(+9)×(+3)=+27
