Log2x - log4x =4

Answer 1

Respuesta:

Log2 X + log 4 X = 2

 

 

  log4 X= m     X = 4^m = 2 ^(2m )

                      Log 4 X = 2 log2 X

 

 

    Log2 X +Log 4 X = Log2 X + 2 Log2 X = Log 2 X + Log 2 X^2 = Log 2 X^3 = Log 2 4

 

    Log (X .X^2)2 = Log2 4

 

     X^3 = 4

 

    X = 3√4

Answer 2

Log2 (x) - Log2^2 (x) = 4
Log2 (x) -1/2 Log2 (x)= 4
1/2Log2(x)= 4
Log2(x) =8
X= 2^8
X=16
