  hello, please, someone help me to correct the equation? It's typed wrong and I can't find where  Solve:  5,76[((log_a ((√(log _b ((√a))))))/(log((√(log(a)))))) + log_(log (a)) (2)]((log _2 (x)))^(1/5)  + ((log_2 (x))/(25)) = [log _2 (x)]^(3/5)   Answers  x_1 =1 , x_2 =2^(243)  , x_3 =2^(−243)  , x_4 =2^(1024)  , x_5 =2^(−1024)

  the equation will be:  5,76[((log((√(log((√((a))) )))/(log((√(log(a))))) +log_(log(a)) (2)](log(x)_2 )^(1/5) +((log_2 (x))/(25))=(log_2 (x))^(3/5)     ((log((√(log((√(a)))))))/(log((√(log(a))))) +log_(log(a)) (2) = [(((1/2)log((1/2)log(a)))/((1/2)log(log(a))))  +((log(2))/(log(log(a))))]  ((log(log(a))−log(2))/(log(log(a))))+((log(2))/(log(log(a))))=1  5,76(log_2 x)^(1/5) +((log_2 (x))/(25))=(log_2 (x))^(3/5)   posons ( log_2 (x))^(1/5) =X  X[5,76+(X^4 /(25))−X^2 =0]⇒X^4 −25X^2 +144=0  Z=X^2     Z^2 −25Z+144=0   Δ=7^2   Z=((25±7)/2)=(9,16)  X=(3,4)  [log_2 (x)]^(1/5) =3    ⇒log(x) =3^5 log(2)^5         x=7,68×10^(16)     x=4     log_2 (x)=4^5       [log(x)=4^5 log(2)^5    x=1,428×10^(71)
