(log6 3)^2+log6 18乘以log6 2急求!!!!!!!!!!!!!!
(log6 3)^2+log6 18乘以log6 2
急求!!!!!!!!!!!!!!
(log6 3)^2+log6 18乘以log6 2急求!!!!!!!!!!!!!!
[log6(3)]²+log6(18)×log6(2)
=[log6(3)]²+[log6(3)+log6(6)]log6(2)
=[log6(3)]²+log6(3)×log6(2)+log6(6)×log6(2)
=[log6(3)]²+log6(3)×log6(2)+log6(2)
=log6(3)[log6(3)+log6(2)]+log6(2)
=log6(3)log6(6)+log6(2)
=log6(3)+log6(2)
=log6(6)
=1
log6 3=log6 (6/2)=log6 6-log6 2=1-log6 2 则log6 2=1-log6 3
log6 18×log6 2=log6 (6×3)×(1-log6 3)=(1+log6 3)×(1-log6 3)=1-(log6 3)²
所以原式=(log6 3)²+1-(log6 3)²=1
(log6 3)^2+log6 18乘以log6 2急求!!!!!!!!!!!!!!
[(1-log6 3)^2+log6 2-log6 18]/log6 4
(log6^4)(log6^18)+2(log6^3)^2
(log6 2)^2+log6 3*log6 12

{(1-log6 3)^2+log6 2*log6 18}/log6 4 等于多少,请写出就算过程,
((1-log6(3))²+log6(2)*log6(18))/log6(4)
[(1-log6 3)²+log6 2×log6 18]/log6 4
(log6^2)^2+(log6^3)*(log6^4)+(log6^3)^2
(log6 3)^2+log6 2+log6 2log6 3=?
计算 (Log6 3)^2+【(log6 18)/(log2 6)]
计算[log6(3)]^2+log6(18)/log2(6)
2^log4(2-根号3)^2+3^log(2+根号3)^2[(1-log6(3)^2+log6(2)*log6(18)]/log6(4)[(1-log6(3))^2+log6(2)*log6(18)]/log6(4)
