log2 36%2log2

log2(36)-2log2(3)=log2(36)-log2(3^2) =log2(36)-log2(9) =log2(36/9) =log2(4) =log2(2^2) =2log2(2) =2

log36=log4+log9=2+2log3

您好是的。

log38-2log36=3log32-2(log32+1)=log32-2,∵a=log32,∴log32-2=a-2.即log38-2log36=a-2.故答案为:a-2.

log6次方36等于2 log2次方4等于2 所以这个题目答案是0

log36(4))/(log18(6))+log^2 6(3) 原式=(log2(4)/log2(36))*(log2(18)/log2(6))+log^2 2(3))/log^2 2(6) =(2/2+2log2(3))*((1+2log2(3))/1+2log2(3))+log^2 2(3))/log^2 2(6) =((1+2log2(3)+log^2 2(3)))/log^2 2(6) =1

运用换底公式 log36 45=log a 45/log a 36 (a代表随意一个底数)

希望对你有所帮助 还望采纳~~
