(log5)+(log2)(log50)的值!急用,谢咯!

高一数学(log5)^2+log2·log50 求值lg2/(log50 10) +lg5/(log5 10) 求下列各式的值 1）log2 6+log2 3 2)lg5+lg2 3)log5 3+log5 三分之一 4）log3 求x的值 log4^x=-2/3 log2^(log5^x)=0 log2 25*log3 4*log5 9 的值为（ ）A 6 B8 C15 D 30 求log2(1\25)×log3(1\8)×log5(1\9)的值 log2/log5等于多少 (Log2)的三次方+(Log5)的三次方+lg8*lg5 (log5)²+lg2*lg5+2的(1+1/2log2为底5的对数)次方 的值 若3/log2 19+2/log3 19+1/log5 19=log19 m,求m的值 (log2)和(log3)变成(log5) log2(5)*log5(8)化简
