1g25+2/3g8+1g5乘1g20+(1g2)的平方
1g25+2/3g8+1g5乘1g20+(1g2)的平方
1g25+2/3g8+1g5乘1g20+(1g2)的平方
原式=lg5²+(2/3)lg2³+lg5×(lg2+lg10)+(lg2)²
=2lg5+2lg2+lg5lg2+lg5+lg2lg2
=2(lg5+lg2)+lg2(lg5+lg2)+lg5
=2×lg10+lg2×lg10+lg5
=2+(lg2+lg5)
=2+1
=3
1g25+2/3g8+1g5乘1g20+(1g2)的平方
对数计算:1g25+三分之二1g8+1g5·1g20+1g平方21g25+三分之二1g8+1g5·1g20+1g平方2 主要是这个1g5·1g20不知怎么办
1g5^2+1g8^(2/3)+1g5·1g20+(1g2)^2=
解(1g2)^3+(1g5)^3+1g5*1g8
(1g2)的二次方+1g20乘以1g5
1g500+1g8/5-1/21g64+50(1g2+1g5)的平方
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?
(log2)2+log2*log50+1g25值
求值:1g8+1g125-1g2-1g5/1g根号下101g0.1等于
若a=1/3(1g16+log5(25)-1g1/5)-1g0.2,b=(1g2)^2+1g2*1g25+(1g5)^2,则a减b等于( )A -1 B 0 C 1 D 2但为什么?
lg5+lg2*1g5+(1g2)^2
化简求值 (1g2)^3+(1g5)^3+3*1g2*1g5
(1g2)^3+(1g5)^3+31g2*1g5=?
如何看G20取代G8
1g2+1g5=
1g2+1g5等于
(lg5)2+1g2*1g25+(1g2)2对数运算,求详尽运算过程!
