2^(log2^(-3))=
(log2 9)/(log2 8) = 2/3(log2 3)
2^(log2^(-3))=
log2 (x + 3) + log2(x + 2) = 1
解方程log2(x+14)-log2(x+6)=3-log2(x+2)
log2 3乘以log2 3等于2log2
log2 3×log3 7=log2 7
log的计算 :log2(20)-log4(25)= log3(2)×log2(5)×log5(3)=?log2[log
log2(x)=-2/3,求x
log2(3)+log3(5)+log3(2)=?
2log5(25)-3log2(64)=?
解方程log2【9^2-4】=log2【3^x-2】+3
log2(1+根号2+根号3)+log2(1+根号2-根号3)=
