Log3 36 - log3 8/27+log 3 18

Log3 36 - log3 8/27 + log 3 18 = Log3 (36/(8/27)) + log 3 18 = Log3 (36 * 27/8) + log 3 18 = Log3 (36 * 27/8 * 18) = Log3 (9 * 27/2 * 18) = Log3 (9 * 27/1 * 9) = Log3 (9 * 27* 9) = Log3 (9 ^ 2 * 3 ^ 3) = Log3 (3 ^ 4 * 3 ^ 3) = Log3 (3 ^ 7) = 7;В итоге получили, Log3 36 - log3 8/27 + log 3 18 = 7.
