化简log2 1/2+log2 2/3+log2 3/4+.+log2 31/32
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)
2^(log2^(-3))=
2^log2 (3) × log2 (1/8) + 2lg3
(log3^4+log5^2)(log2^9+log2^根号3)
不等式log2(2x+3)>log2(x+1)的解集是
log2 (x + 3) + log2(x + 2) = 1
log2(√1/48)+log2 12-1/2log2 (24)-1/3
log2 SQR(7/48)+log2 12 -1/2log2 48
log2 SQR(7/48)+log2 12 -1/2log2 42
log2 3/log2 5等于log2 3-log2 5么?
