2log(2)根号30-log(2)3-log(2)5 求值
2log(2)根号30-log(2)3-log(2)5 求值
2log(2)根号30-log(2)3-log(2)5 求值
2log(2)根号30-log(2)3-log(2)5
=log₂(√30)²-log₂(3×5)
=log₂30-log₂15
=log₂(30/15)
=log₂2
=1

2log(2)根号30-log(2)3-log(2)5 求值
log(根号2-1)(3
log(2)根号18+1/2log(2)56-log(2)3根号7
log(3)1+log(2)根号2+lg1000
log(27)32 × log(64)27+log(9)2 × log(4)根号27=?log(27)32 × log(64)27+log(9)2 × log(4)根号27=?
log(2)(25)*log(3)(根号2)*log(5)(9)+_+ 请问为什么错?
(log^2根号3)^2咋解
log根号2sin5/12
log根号2（X-1)
log(1/根号2)16
log(根号3+根号2) (根号3-根号2) 求值.
log(2)9log(3)4等于
log(2)9×log(3)4
4^[log(2)3+log(4)8]
[log(3)3^1/2]^2+log(0.25)1/4+9log5根号5-log（根号3）1=?
log底数2^（2+根号3）+log底数2^（2-根号3）
log(2/3)81-log(2/3)16+log(2/3)20-log(2/3)30=?写下换算过程,
