To prove that a^log c base b=c^log a base b
we can use the change of base formula for logarithms and some properties of exponents.
Given:
a^log c base b
We know that
log c base b = log c base a/log b base a (Change of base formula).
So, we can rewrite the expression as:
a(log c base a/ log b base a)
Using the property of exponents
(a^m)^n=a^mn, we can rewrite the expression as:
(a^ log c base a)1/log b base a
(c)^ 1/log b base a
Now, we need to find c^log b base a:
c^log b base a =(b^log c base b)^log a base b
(b^ log b base a)^ log c base b
(a)^log c base b
Now, comparing this result with the expression we got earlier, we see that they are equal:
c^ log a base b =(a)^ log c base b
Hence, a^log c base b=c^log a base b is proved.
