[(1-log6底3)^2+log6底2*log6底18]÷log6底4=
原式={[log6(6)-log6(3)]²+log6(2)*log6(18)]÷log6(4)
={[log6(6÷3)]²+log6(2)*log6(18)}÷log6(4)
={[log6(2)]²+log6(2)*log6(18)}÷log6(4)
={log6(2)*[log6(2)+log6(18)]}÷log6(4)
=log6(2)*[log6(2×18)]÷log6(4)
=log6(2)*[log6(6²)]÷log6(4)
换底公式
=(lg2/lg6)*2÷(lg4/lg6)
=2lg2÷lg4
=2lg2÷2lg2
=1
={[log6(6÷3)]²+log6(2)*log6(18)}÷log6(4)
={[log6(2)]²+log6(2)*log6(18)}÷log6(4)
={log6(2)*[log6(2)+log6(18)]}÷log6(4)
=log6(2)*[log6(2×18)]÷log6(4)
=log6(2)*[log6(6²)]÷log6(4)
换底公式
=(lg2/lg6)*2÷(lg4/lg6)
=2lg2÷lg4
=2lg2÷2lg2
=1
[(1-log6底3)^2+log6底2*log6底18]÷log6底4=
[(1-log6 3)^2+log6 2-log6 18]/log6 4
[(1-log6(3))^2 + log6(2) × log6(18)]÷log6(4)
((1-log6(3))²+log6(2)*log6(18))/log6(4)
[(1-log6 3)²+log6 2×log6 18]/log6 4
{(1-log6 3)^2+log6 2*log6 18}/log6 4 等于多少,请写出就算过程,
(log6^2)^2+(log6^3)*(log6^4)+(log6^3)^2
化简[(1-log6^3)^2+logb^2×log6^18]÷log6^4如题
(log6 3)^2+log6 18乘以log6 2
log6 2*log6 18+log6 81/4log3 6
[log6(底)3(真)]2(方)+log6(底)18(真)·log6(底)2(真)
(log6(2))^2+log6(2)*log6(3)+log6(18)的值
