5^(log25((lg2^2)+lg5/2))

5^(log25((lg2^2)+lg5/2)) 5^log25(lg2-1)^2=? lg^2 5+lg2*lg5+lg2=? 对数的运算化简：1 lg5方+(2/3)lg8+lg5lg20+(lg2）方 2 (log2 5+log4 0.2)(log5 2+log25 0.5) 关于对数运算（lg5）^2+lg2·lg50=?(log2 125+log4 25+log8 5)·(log125 8+log25 4+log5 2)=? log25+lg2*log50+(log2)^2 lg^2 5+lg5*lg2+lg2 怎么算lg^2 5+lg5*lg2+lg2 怎么算 高一对数运算.(1)lg25+(lg2)^2+lg2*lg5(2)lg2*lg50+lg5*lg20-lg100*lg5*lg2(3)(log2 5+log4 0.2)*(log5 2+log25 0.5) [2,4,5,25,是底数]写写过程．．．很急的,明早要交.不一定要做3题,做多少都行.快啦........第一题打错 lg2(1+lg5)+(lg5)^2 计算：(lg5)^2 +lg2 *lg5 (lg5)^2+lg5.lg2= 2lg2（lg2+lg5)+2lg5得数 (lg2)^2+lg2*lg5+(lg5)^2= lg2*lg50+lg5*lg20-2lg5*lg2 (lg5)平方+2*lg5*lg2+(lg2)平方 对数lg2*lg5=?2lg（5）+2/3 lg8+lg5*lg20+lg2 =lg5^2+lg8^(2/3)+lg5*(lg4+lg5)+lg2 =lg100+lg5+2lg2*lg5+lg2 =2+(lg5+lg2) =2+1 =3 第二个等号lg5*(lg4+lg5)为什么=lg5+2lg2*lg5 求值 ：lg5²+lg2*lg50+(lg2)²答案写；2lg5+lg2*lg(5*10)+(lg2)²①=2lg5+lg2*lg5+lg2+(lg2)² ②=2lg5+lg2*(lg5+lg2)+lg2③ .第 ②步怎么得到的怎么就变成了lg2*lg5+lg2? lg5×lg(5×2)+lg2怎莫算具体
