(lg5)^2+lg2lg50(lg5)^2+lg2lg50(lg5)^2+lg2lg50(lg5)²+lg2lg50=(lg5)²+lg2(lg5²+lg2)=(lg5
(lg5)^2+ lg2lg50
(lg5)^2+ lg2lg50
(lg5)^2+ lg2lg50
(lg5)²+ lg2lg50
=(lg5)²+lg2(lg5²+lg2)
=(lg5)²+2lg2lg5+(lg2)²
=(lg5+lg2)²
=[lg(5x2)]²
=1
结果为1
过程lg5×lg5+lg2×(lg5+lg10)
=lg5×(lg5+lg2)+lg2
=lg5+lg2
=1
(lg5)^2+ lg2lg50
lg5^2+lg2lg50-lg0.001
(lg5)^2+lg2lg50怎么算?
计算2^(1+1/2log2 5)+(lg5)^2+lg2lg50
(lg5)的平方+lg2lg50是多少?
(lg5)²+lg2lg50=
lg2lg50+lg5×lg20-lg100×lg5×lg2=
计算:(lg5)^2+lg2lg50+2^((1+1/2(log2(5))))
对数运算 lg^2+lg2lg50的 5201314food 请问为什么lg^2=(lg5)^2
lg4怎么等于1了!有2个式子:lg25+lg2lg50(①式) lg25+lg2lg50+lg4(②式)=lg5^2+lg2(lg5+lg10) =2lg5+lg2(lg50+lg2)=lg5^2+lg5lg2+lg2 =2lg5+lg100lg2=lg5(lg5+lg2)+lg2 =2(lg5+lg2)=lg5x1+lg2 =2x1=lg5+lg2 =2=1那么②式-①式=lg25+lg2lg50
lg25+lg2lg50+(lg2)2
lg5的平方+lg2lg50+2d的(1+二分之一倍log以2为底5的对数)次方 =无视我的答案
lg25+lg2lg50+(lg2)2
lg25+2lg2lg50等于多少?
一道数学题-高一的函数1‘式子lg²5+lg2lg50的值?2’求值:lg5(lg8+lg1000)+(lg2√³)²+lg1/6+lg0.06
(lg5)^2+lg2lg50+2^((1+1/2(log2(5))))=2+2√5?=(1-lg2)^2+lg2lg10+1-lg2+2√5注注lg5=1-lg2
lg25+lg2lg50+(lg2)^2=THANKS.
