²log 4 – ²log 6 + ²log 12
= 2log 2² + ²log 12 – ²log 6
= 2 + ²log (12 : 6)
= 2 + ²log 2
= 2 + 1
= 3

2log4=2
2log12=2+2log3
2log6=1+2log3
2+2+2log3-1-2log3= 3

²log 4.12.6

= ²log 288

= ² log12²×2

= 2.²log12 + ²log2

= 2.²log 4.3 +²log2

= 2.²log 4 + ²log3+ ²log2

=2.2+²log3+1

= 5+²log3

²log 4 + ²log 12 – ²log 6 = ²log (4×12:6)
      = ²log 8
      = ²log 2³
      = 3 ²log 2
      = 3
