pakai cara yaa,,, :) makasih

⁴log(⁴log x)-⁴log(⁴log(⁴log 16))=2
⁴log(⁴log x)-⁴log(⁴log(⁴log 4²))=2
⁴log(⁴log x)-⁴log(⁴log(2 ⁴log 4))=2
⁴log(⁴log x)-⁴log(⁴log 2)=2
⁴log(⁴log x)-⁴log(½ ²log 2)=2
⁴log(⁴log x)-⁴log ½ =2
⁴log(⁴log x)-⁴log 2^(-1) =2
⁴log(⁴log x)- (-½) ²log 2=2
⁴log(⁴log x)+½=2
⁴log(⁴log x)=3/2
⁴log x = 4^3/2
⁴log x = 2^(2×3/2)
⁴log x= 2³
⁴log x =8
x=4^8

^16log x
=⁴^²log 4^8
=8/2 ⁴log 4
=4
