Answer :
log(1/216)^(x+2) = log 6^12
(x+2) log(1/216) = log 6^12
xlog(1/216) + 2log(1/216) = log6^12
xlog(1/216) = log6^12 - 2log(1/216)
x = [log6^12-2log(1/216] / log(1/216)
x = -6
(x+2) log(1/216) = log 6^12
xlog(1/216) + 2log(1/216) = log6^12
xlog(1/216) = log6^12 - 2log(1/216)
x = [log6^12-2log(1/216] / log(1/216)
x = -6
