化简算式log2^√7/48+log2^12-1/2log2^42+1/2^log2^3化简算式log2^√7/48+log2^12-1/2log2^42+1/2^log2^3化简算式log2^√7/
化简算式log2^√7/48+log2^12-1/2log2^42+1/2^log2^3
化简算式log2^√7/48+log2^12-1/2log2^42+1/2^log2^3
化简算式log2^√7/48+log2^12-1/2log2^42+1/2^log2^3
=1/2log2^7-log2^48+log2^12-1/2log2^42+1/3
=1/2log2^(1/6)+log2^(1/4)+1/3
=-1/2log2^6-2+1/3
=-1/2log2^6-5/3
不知道是不是这样.
化简算式log2^√7/48+log2^12-1/2log2^42+1/2^log2^3
log2[√(7/48)]+log2(12)-log2(√42)
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 SQR(7/48)+log2 12 -1/2log2 48
log2 SQR(7/48)+log2 12 -1/2log2 42
log2 √7/24+log2 12-log442
Log2√（7/48） +log2 12 -（1/2）log2 42要详细点的额
log2(log2
1/2log2(7/48)+log2 12-1/2log2 42log2 的2 在g的右下脚
化简根号下[(log2^3)^2-4log2^3+4]+log2^(1/3)
log2底√1/48+log2底12-1/2log2底24等于?
log2（√1/48）+log2 12-1/2log2 （24）-1/3
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(3)×log2(4)=log2(7)?log2(3)×log2(4)=log2(7)吗?log2(1/49)+log2(1/16)+log2(1/27)等于多少呢?帮个忙!
log2^(4^7*2^5)+log2^6-log2^3
