求[lg^2(5)-lg^2(2)/lg25-lg4]*log(1/2)1/4+8^[log(4)(3/5)^2]的值求[lg^2(5)-lg^2(2)/lg25-lg4]*log(1/2)1/4+8
求[lg^2(5)-lg^2(2)/lg25-lg4]*log(1/2)1/4+8^[log(4)(3/5)^2]的值
求[lg^2(5)-lg^2(2)/lg25-lg4]*log(1/2)1/4+8^[log(4)(3/5)^2]的值
求[lg^2(5)-lg^2(2)/lg25-lg4]*log(1/2)1/4+8^[log(4)(3/5)^2]的值
[lg^2(5)-lg^2(2)/lg25-lg4]*log(1/2)1/4+8^[log(4)(3/5)^2]
=[(lg(5)+lg(2))(lg(5)-lg(2))/2(lg5-lg2)]*log(1/2)(1/2)^2+2^3[log(4)(3/5)^2]
=[(lg(5)+lg(2))/2]*2+2^2[log(4)(3/5)^3]
=(1/2)*2+4^[log(4)(3/5)^3]
=1+(3/5)^3
=1+27/125
=152/125
lg 5 lg 20-lg 2*lg 50-lg 25
求值 lg 2lg 50 + lg 5lg 20 - lg 100lg 5lg 2
求值(lg 2)^2 lg 2lg 5 lg 50
3lg 2 lg 5
lg 5-lg 2-2lg 5=
lg√2+lg√5+lg√10
lg平方5+lg21g25+lg平方2 求计算,
lg^2^5+lg^2乘lg^5+lg^2等于多少?
lg(5)+lg^2(2)+lg(2)×lg(5)=?有过程加分
[(lg^5)^2-(lg^2)^2]÷(lg^25-lg^4)=?可我就是不会.
lg^3(2)+lg^3(5)+3lg(2)*lg(5)化简
lg 5(lg 8+lg 1000)+( 3lg 2)²;计算
已知log14 7=a,log14 5=b,求log35 28(用a,b表示)log 14 7 = lg 7 / lg 14 log 14 5 = lg 5 / lg 14 A = lg 7 / lg 14 = lg 7 / (lg 7 + lg 2) B = lg 5 / lg 14 = (1 - lg2) / (lg 7 + lg 2) 通过以上两式可得:lg 7 = A / (1 - A + B) lg 2 = (1 - A) / (
求不等式lg(x-2)+lg(4-x)
求不等式lg(x-2)+lg(4-x)
lg∧2(5)+lg(2)+lg(50)不好意思,应该是lg∧2(5)+lg(2)*lg(50),
lg(2-2x)-lg(x+1)
[(lg√27+lg^8-3lg√10]/lg^(1.2)计算2)lg^25+lg^2*lg^25+2(lg^2)^2
