1、拜求这道题的值啊:1g8+1g125-1g2-1g5/1g根号下101g0.1等于,2、log2的25log3的81log5的9等于?3.(log4的3+log8的3）乘以1g2/1g3等于?4.1g8+31g5等于？
1g5^2+1g8^(2/3)+1g5·1g20+(1g2)^2=
解(1g2)^3+(1g5)^3+1g5*1g8
化简求值 (1g2)^3+(1g5)^3+3*1g2*1g5
1g500+1g8/5-1/21g64+50(1g2+1g5)的平方
1g25+2/3g8+1g5乘1g20+(1g2)的平方
(1g5)+21g2-(1g2)
1g2+1g5=
1g2+1g5等于
lg5+lg2*1g5+(1g2)^2
1g5-1g2份之一 计算
1g5+1g2等于多少.
(1g2)^3+(1g5)^3+31g2*1g5=?
(1g2)的二次方+1g20乘以1g5
计算(1g5)2+1g2*1g50=多少?
计算2sin180°-1g5-1g2?有急用
对数计算（1g2）²+1g5·lg20
