log2[√(7/48)]+log2(12)-log2(√42)
log2 SQR(7/48)+log2 12 -1/2log2 48
log2 SQR(7/48)+log2 12 -1/2log2 42
Log2√(7/48) +log2 12 -(1/2)log2 42要详细点的额
log2 √7/24+log2 12-log442
化简算式log2^√7/48+log2^12-1/2log2^42+1/2^log2^3
求值:log2√(7/48)+log2(12)-1/2log2(42)-1 这道题我算来算去算不对
计算log2 √(48/7)-log2 12+(1/2)log2 42-1
log2(√1/48)+log2 12-1/2log2 (24)-1/3
1/2log2(7/48)+log2 12-1/2log2 42log2 的2 在g的右下脚
log2底√1/48+log2底12-1/2log2底24等于?
log2(根号下7/48)+log2(12)-1/2log2(42)-1=?
log2根号7/48+log2^12-1/2log2^42-1=
求化简log2根号下48分之7+log2 12-log2 42
log2(12)-log23
2log2(12)怎么转化成log2(3)?
log2(log2
如何把2log2 7转化为 2(log2 14)-log2 2
