a^log(a) b = b
log(25) 1/4 = log(5^2) (1/2)^2 = 2*1/2 log(5) 1/2 = log(5) 1/2
a^(m+n)=a^m*a^n
5^(2 + log(25) 1/4) = 5^2 * 5^log(5) 1/2 = 25*1/2 = 25 / 2 =12 1/2 = 12.5

a^log(a) b = b
log(25) 1/4 = log(5^2) (1/2)^2 = 2*1/2 log(5) 1/2 = log(5) 1/2
a^(m+n)=a^m*a^n
5^(2 + log(25) 1/4) = 5^2 * 5^log(5) 1/2 = 25*1/2 = 25 / 2 =12 1/2 = 12.5
