log (3) x=4log (3) 3-2log (3) 4

log (3) x = 4log (3) 3 - 2log (3) 4

x>0

log (3) x = log (3) 3^4 - log (3) 4^2

log (3) x = log (3) 3^4/4^2

x = 3^4/4^2 = 81/16 = 5 1/16

k log (a) b = log (a) a^k

log (a) b - log (a) c = log (a) b/c

Log (3) x=4+log (3) 4^-2

log (3) x=log (3) 3^4+log (3) 4^-2

log (3) x=log (3) 3^4*4^-2

log (3) x=log (3) 81*1 (4^2)

log (3) x=log (3) 81/16

x=81/16

x=5,1/16
