If a is the logarithm of the bottom 3 / 4 < 1, (a > 0 and a is not equal to 1), find the value range of the real number a?

If a is the logarithm of the bottom 3 / 4 < 1, (a > 0 and a is not equal to 1), find the value range of the real number a?

If the logarithm of the base 3 / 4 of a is less than 1
I.e. logo (3 / 4)
