2log3 2-log3 32/9+log3 8-3^2+log3 5
2log3 2-log3 32/9+log3 8-3^2+log3 5
2log3 2-log3 32/9+log3 8-3^2+log3 5
2log₃ 2-log₃(32/9)+log₃8-3^(2+log₃5)
=log₃4-log₃(32/9)+log₃8-3^2*3^log₃5
=log₃(4÷32/9×8) -9*5
=log₃(4×9/32×8)-45
=log₃9-45
=2-45
=-43
最后的式子指数应该加括号,试了半天

2log3 2-log3 32/9+log3 8-5^2log5 3
2log3^2-log3^(32/9)+log3^8 怎么化简?
2log3 (2)-log3(32/9)+log3(8)-3详细解答!
log3 18-log3 2=log3 16?
log3(2)*log8(9)
2log3^2-log3^(32/9)+log3^8-5log5^3=5log5^3改成5^log5^3
求值:2log3(这个3是角标）2-log3（角标）32/9+log3（角标）8-5log
