若log3(7)*log2(9)*log49(a)=log4(1/2),则a=?若log3(7)*log2(9)*log49(a)=log4(1/2),则a=?若log3(7)*log2(9)*log
若log3(7)*log2(9)*log49(a)=log4(1/2),则a=?
若log3(7)*log2(9)*log49(a)=log4(1/2),则a=?
若log3(7)*log2(9)*log49(a)=log4(1/2),则a=?
log3(7)*log2(9)*log49(a)=log4(1/2)
=lg7/lg3*2lg3/lg2*lga/2lg7=-lg2/2lg2
=lga/lg2=-lg2/2lg2
=lga=lg根号2^(-1)
a=根号2^(-1)=根号2/2
(log3 4+log3 8)(log2 3+log2 9)+(log3 根号2)(log9 7)/(log1/3 7)(log三次根号4 8)
log2^9*log3^8
[log3(4)+log根下3(2)][log2(9)+log4(根3)]
(log2 5+log4 125)log3 2/ log根号3 5
若log3(7)*log2(9)*log49(a)=log4(1/2),则a=?
亲.3^(log3^6)-2^4+log2^3+10^3lg^3 +(1/9)^3^(log3^6)-2^4+log2^3+10^3lg^3 +(1/9)^(log3^4^-1)-log(2+√3)^(7-4√3)
log3^7乘以log2^9乘以log49^2=
log3^7乘以log2^9乘以log49^2=
若log2 3×log3 6×log6 m=log3 27,则m=紧贴log的是底数,空格之后的是真数
设log3;7=a,log2;3=b则LOG2;7=LOG后面的3,2,2均为角标
已知log(32)9=p,log(27)25=q,适用p,q表示lg5p=log32(9)=2/5×log2(3)=2/5×1/log3(2)∴log3(2)=2/5pq=log27(25)=2/3×log3(5)∴log3(5)=3q/2lg5=log3(5)/log3(10)=log3(5)/[log3(2)+log3(5)]=15pq/(4+15pq)结果怎么出来的?
比大小.log2 7 和log3 7
log2 9乘以log3 4等于多少
怎么算log2 9乘log3 2
log2 9×log3 2怎么算?
Log2013[Log2(log3的9次方)_
log2^3*log3^7*log7^8
log2 3×log3 7=log2 7这个算法对吗
