log 4 (2x+4) - 3 =log 4 3 log 4 (2x+4) - 3log 4 4 = log 4 3 log 4 (2x+4) - log 4 4^3 = log 4 3 log 4 [(2x+4)/64] = log 4 3 (2x+4)/64 = 3 2x+4 = 192 2x=188 x = 94

log4(2x+4)-3 =log4 3

1 answer

log₄(2x+4) - 3 =log₄ 3
log₄(2x+4) - 3log₄4 = log₄ 3
log₄(2x+4) - log₄ 4^3 = log₄3
log₄[(2x+4)/64] = log₄3
(2x+4)/64 = 3
2x+4 = 192
2x=188
x = 94
