Hiii
could someone help me ?!
I have this problem and I solved it but I'm not sure if my answer is correct
so I just want you to tell me if it's correct or not
and if it wasn't correct .. maybe you can help me find the correct answer
well .. ok
log { base 4 } of x = 25 log { base x } of 4
log { base 4 } of x = 25/[log { base 4 } of x]
log { base 4 } of x - 25/[log { base 4 } of x] = 0
let' say that K = log { base 4 } of x
K - 25/K = 0
(K)K - (K)25/K = (K)0
(K^2) - 25 = 0
K^2 = 25
K = 5
log { base 4 } of x = 5
x = 4^5
x = 1024
is my answer correct ?!
