It is an identity that logₐ aˣ ≡ xL.H.S.
= logₐ aˣ
= x * (logₐ a)
= x * (1)
= x
= R.H.S.
Thus, logₐ aˣ ≡ x

log(base a) a^x = x log(base a) a = x (1) = x
Did you mean to ask "Why is loga a^x=x?"

Lt log be log to base a
x log a = x x 1 = x
x log a = x x 1 = x

log( a)=1
x log (a)=x
a<0, x=0
a=e
a>0, x=0
x=0
x log (a)=x
a<0, x=0
a=e
a>0, x=0
x=0
