log2 3/log2 5等于log2 3-log2 5么?
log2 5/4+log2 5
根号下{[log2 （5)]^2-4log2(5)+4}+log2(1/5)
根号下[(log2^3)^2-4log2^3+4]+log2^(1/3)
log2 3乘以log2 3等于2log2
(log2 9)/(log2 8) = 2/3(log2 3)
log2 SQR(7/48)+log2 12 -1/2log2 48
log2 SQR(7/48)+log2 12 -1/2log2 42
2^(log2^(-3))=
log2(20)-log2(5)+2log3(2)×log4(3)
2^log2 (3) × log2 (1/8) + 2lg3
(log3^4+log5^2)(log2^9+log2^根号3)
