(lg3)^2+(lg3)^5+lg8*lg5等于?
(lg3)^2+(lg3)^5+lg8*lg5等于?
(lg3)^2+(lg3)^5+lg8*lg5等于?
lg3=0.47712125471966243729502790325512
lg8=0.90308998699194358564121668417348

(lg3)^2+(lg3)^5+lg8*lg5等于?
(lg3/lg4+lg3/lg8)(lg2/Ig3+lg2/lg9)这题计算过程
(2lg2+lg3)/(1+1/2lg0.36+1/3lg8)
计算(2lg2+lg3)/(2+lg0.36+2/3lg8)
计算lg14-2lg3分之7+lg7-lg8
(log23+lOg427)(log34+log98)= 23中2是底数3是真数,4是底数,3是底数,9是底数(log23+lOg427)(log34+log98)=(lg3/lg2+lg27/lg4)(lg4/lg3+lg8/lg9)=(lg3/lg2+3lg3/2lg2)(2lg2/lg3+3lg2/2lg3)=(5lg3/2lg2)(7lg2/2lg3)=(5/2)(7/2)=35/4为什么(lg3/lg2+3lg
(lg1+lg2+lg3+lg4+lg8+``````+lg1024)
化简(log4(3)+log8(3))(log3(2)+log9(2))(log4(3)+log8(3))(log3(2)+log9(2))=(lg3/lg4+lg3/lg8)(lg2/lg3+lg2/lg9)=5lg3/6lg2X3lg2/2lg3=5/6X3/2=5/4可是是怎样从第一步到第二步的?
lg3次方根号下2+lg3次方根号下5
(lg3分之2lg2+lg3分之3lg2)(lg2分之lg3+lg2分之2lg3)(2lg2分之lg3+3lg2分之lg3)(lg3分之lg2+2lg3分之lg2) 是这个上面那个大错了谢谢
(2lg2+lg3)/[1+(1/2)lg0.36+(1/3)lg8]需要一点小小的过程
计算下列公式 (1)(2lg2+lg3)/(1+1/2lg0.36+1/3lg8) (2) lg5^2+2/3lg8+lg5*lg20+(lg2)^2
lg25+2/3lg8+lg5×lg20+^2=多少?lg2×lg3/lg^2=多少?
(2lg2+lg3)/[1+(1/2)lg0.36+(1/3)lg8]等于什么
{√[(lg3)^2-lg9+1] *(lg√27+lg8-lg√1000)}/(lg0.3*lg1.2)
求1+1/2lg0.36+1/3lg8分之2lg2+lg3的值
2lg2+lg3除以1+1/2lg0.36+1/3lg8等于多少?
求2lg2+lg3/1+1/2lg.36+1/3lg8的值
