(根号2-1)(lg1)lg1是次方 我知道答案是1,
(25/16)^(-1/2)+lne^2+C(5,4)-(1-根号7)lg1+sinπ
计算log2.5(6.25)+lg1/100+In根号下e+2[1+log2(3)]
(lg3+2lg2-1)除以lg1.2=?
(lg根号27+lg8-lg根号1000)/lg1、2
(lg根号27+lg5-lg10根号2)/lg1.5
计算:1/(根号0.25)+(1/27)^-1/3+根号[(lg3)^2-lg9+1]-lg1/3+81^0.5log3
1题 (lg根号2+lg3-lg根号10)/lg1.8
(log3 2)+log9 2)*(log4 3+log8 3)+(log3 3^1/2)^2+ln根号e-lg1
(4/9)0.5方+(-5.6)lg1方-(2又10/27)-2/3方+0.125-1/3方
根号下{(lg3)平方-lg9+1}乘以(lg根号下27+lg8-lg根号下1000)再整体除以lg0.3乘以lg1.2
【根号(lg的平方3-lg9+1)*(lg根号27+lg8-lg根号1000)】/(lg0.3)*(lg1.2)
【根号(lg3的平方-lg9+1)*(lg根号27+lg8-lg根号1000)】/(lg0.3)*(lg1.2)
