已知log5(根号6+1)+log2(根号2-1)=a,则log5(根号6-1)+log2(根号2+1)=
log2^25*log3^2倍根号2*log5^9=
log2^5*log3^2倍根号2*log5^9=
(log3^4+log5^2)(log2^9+log2^根号3)
log2(1+根号2+根号3)+log2(1+根号2-根号3)=
log2(1+根号2+根号3)+log2(1+根号2 -根号3)
对数 log5(35)+2log1/2( 根号2)-log5(1/50)-log5(14)
log2x^2=log2(根号2-1)-log2(根号2+1),求x+1/x
log5[log根号2-1(1/根号(3+2根号2))] 等于多少?
2(lg根号下2)^2+(lg根号下2)(lg5)+|lg根号下2-(log2底5)(log5底2)|=?
log2(根号下7/48)+log2(12)-1/2log2(42)-1=?
计算log2 6-log2 3,lg5+lg2,log5 3+log5 1/3,log3 5-log3 15
[log(3)3^1/2]^2+log(0.25)1/4+9log5根号5-log(根号3)1=?
