Solve using "log rules":
4log4+logx=6
log4^2+logx=6
log16+logx=6
log(16x)=6
16x = 10^6
x = 10^6/16
x = 62500

4log4+logx=6
log4^4+logx=6
to add logs is to multiply
log (4^4*x)=6
log256x=6
raise to power of base 10
10^log(256x)=10^6
256x=10^6=1000000
x=1000000/256=3906.25
check
4log4+log3906.25=6
2.4082+3.5918=6
6=6
