log9^6和log4 ^6等于
log9^6=6log3^2=12log3
log4 ^6=6log2^2=12log2
再问: 他们的倒数和是多少....谢谢
再答: 1/log9^6+1/log4 ^6=-12log3-12log2 =-12(log3+log2 )==-12log6
log4 ^6=6log2^2=12log2
再问: 他们的倒数和是多少....谢谢
再答: 1/log9^6+1/log4 ^6=-12log3-12log2 =-12(log3+log2 )==-12log6
[log2(3)+log4(9)][log3(4)+log9(2)]等于

log9^8×log4^27=____.
(log9(8))*(log4(3根号3))?
[log4(3)/log4(8)][log3(2)log9(2)]
log5^6×log6^7×log7^8×log8^9×log9^10等于多少?
计算log9(根号2)*[log4(3)+log8(3)]
计算:(log4 3+log8 3)×log9 √2=?
