Step-by-step explanation:
Think about it for a second.
Take log 3 (-9). 3 to what power is -9.
Let's try:
3 ^ 2 = 9. So it's not negative 9.
Maybe 3 ^ -2 = 1/9. Still not -9.
Let's try 3 ^ 1/3 = 1.4422. Still not remotely close.
So we can make a conclusion that a positive number to any real exponent can't give us a negative number.
