log[(根号2)/2] 4 = 应该看得懂吧?[(根号2)/2] 是底数,4是真数
log[(根号2)/2] 4 = 应该看得懂吧?[(根号2)/2] 是底数,4是真数
log[(根号2)/2] 4 = 应该看得懂吧?[(根号2)/2] 是底数,4是真数
-4
log(2^-1/2)2^2
=2/(-1/2)*1
=-4
log[(根号2)/2] 4
=lg4/lg[(根号2)/2]
=2lg2/(-1/2lg2)
=2/(-1/2)
=-4
底数:二分之根号二等于2的(-1/2)次方。
底数的次方数可以提到log前,4等于2的平方,平方数也可以提到log前,就得到2*(-1/2)=-1.
log(2)2=1
最终答案是-1
log[(根号2)/2] 4
=lg4/lg[(根号2)/2]
=2lg2/(-1/2lg2)
=2/(-1/2)
=-4
log(2^-1/2)2^2
=2/(-1/2)*1
=-4
两种都行
log[(根号2)/2] 4 = 应该看得懂吧?[(根号2)/2] 是底数,4是真数
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(3)3^1/2]^2+log(0.25)1/4+9log5根号5-log(根号3)1=?
化简2log`5(10)+log`3(0.25)+log`1/5(125)=(2) log`2(根号2)+log`9(27)+(1/4)^log`4(1/16) 注意 `为下角标
(LOG(3,4)+LOG(3,8))(LOG(2,3)+LOG(2,9))等于几 看的懂吧
已知0<a<1,x=log a 根号2+log a 根号3y=1/2 log a 5z=log a 根号21 -log a 根号3比较x y z 的大小关系x=log a (根号2)+log a (根号3)y=1/2 (log a 5)z=log a (根号21) -log a (根号3)
求 log 根号2 1/3,看图.
log(0.1)log(0.2)log(0.5)(1/根号5次2)=x,求x的值
计算题(log)已知log底数5 ^2=a,log底数5 ^3=b求log底数5根号54 的值
log(根号2分之1)为底16=
已知log(2)[log(3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x+y的值
若log(根号2减1)=-1,则x=log x (根号2减1)
已知log a (x^2+4)+log a (y^2+1)=log a (2xy-1)(a>0,且a≠1),求log 根号下2 x/y的值有些数学符号没办法打,见谅~
计算 log23*log3 1/2计算log(根号2)2*根号2+log(2)3*log(3)1/2=()中的为底数 后面的为真数,
求1/2log(10)(x+6)加log(10)(根号2x+5)=log(10)(6根号2)
log底数2^(2+根号3)+log底数2^(2-根号3)
化简log根号2(sin7π/8)+log根号2(sin3π/8)
若log底数2[log底数3(log底数4)]若log底数2[log底数3(log底数4(x))]=log底数3[log底数4(log底数2(y))]=log底数4[log底数2(log底数3z)]=0,则x+y+z=
