化简 (log36(4))/(log18(6))+log^2 6(3)
log^2 6(3) 以6为底 3为真数

化简 (log36(4))/(log18(6))+log^2 6(3)log^2 6(3) 以6为底 3为真数
(log36(4))/(log18(6))+log^2 6(3)
=(lg4/lg36)/(lg6/lg18)+lg^2(3)/lg^2(6)
=2lg2/(2lg2+2lg3)/[(lg2+lg3)/(lg2+2lg3)]+[lg3/(lg2+lg3)]^2
=lg2/(lg2+lg3)/[(lg2+lg3)/(lg2+2lg3)]+[lg3/(lg2+lg3)]^2
=lg2×(lg2+2lg3)/(lg2+lg3)^2+[lg3/(lg2+lg3)]^2
=[(lg2)^2+2lg2lg3+(lg3)^2]/(lg2+lg3)^2
=(lg2+lg3)^2/(lg2+lg3)^2
