    The output of log is highly dependent upon the value of a or base
    If value of a is grater than one and the value of input is greater than one
    We will get positive values
    And if the values of a is more than one and value of input is less than one(excluding negative and zero) we get negative values
    Vice versa
    If values of a is less than one and value of input is more than one
    We will get negative values
    And is value of a is less than one and value is also less then one(excluding negative and zero)we get positive values

    Jab base 1 se bada hoga ya chota aur input 1 se chota ya bada respectively. Tab negative output hoga.
    Jab base 1 se bada hoga aur chota aur input bhi bada hoga air chota respectively tab output negative hoga.
    In short for negative output (bada,chota ),(chota bada )
    Positive (bada ,bada ),(chota bada )
    Bada means more than 1
    Chota means less than 1 and more than zero.

    The output y is negative when the base a or the input x or both are less than 1
    &
    The output is positive when both the input x as well as base a is more than 1 or equal to 1.

    For log(x), x being any number, log(x)=0 if x=1.
    For values less than 1, it gives negative. Example, log(100) taking base 10 is 2. This is positive. If we take 0.1( which is 10 to the power -1), we get log(0.1)=-1.
    So if the number is proper fraction,ie: it lies between 0 and 1, logarithm is negative. Anothe example, For base 2,log(0.25)=-2 because 0.25= 2^-2. This is genaralized as for 0

    Output is -ve : when input is less than base but greater than 0.
    Output is 0 : when input is 1 anything be the base.
