(Log2)的三次方+(Log5)的三次方+3*lg2*lg5=?
(Log2)的三次方+(Log5)的三次方+3*lg2*lg5=?
(Log2)的三次方+(Log5)的三次方+3*lg2*lg5=?
(log2)^3+(log5)^3+3lg2lg5
=(log2+log5)((log2)^2-log2log5+(log5)^2)+3log2log5
=log(2*5)((log2)^2+2log2log5+(log5)^2-3log2log5)+3log2log5
=log10((log2+log5)^2-3log2log5)+3log2log5
=1*((log10)^2-3log2log5)+3log2log5
=(1-3log2log5)+3log2log5
=1
(Log2)的三次方+(Log5)的三次方+lg8*lg5
(Log2)的三次方+(Log5)的三次方+3*lg2*lg5=?
求(log2)^3+(log5)^3+log5×log8的值.
(log5)+(log2)(log50)的值!急用,谢咯!
(1/2)的(log2底5)次方还有[2的(log2底5)次方]+37的(1-log2底3)次方5的(log√5底2)次方log5底1+log3底3+lg三次根号100帮忙写一下过程还有log3底75
第五题,log2的25次方•log3的4次方•log5的9次方的值为?
