log9 ((4^更号27)/3)+lg 20+log100 25+5^(log5 2)对数计算
log9 ((4^更号27)/3)+lg 20+log100 25+5^(log5 2)对数计算
log9((⁴√27)/3)+lg 20+log100 25+5^(log5 2)
=1/2log₃(⁴√27/3)+lg20+2/2* lg5+2
=1/2[log₃⁴√27-log₃3]+lg100+2
=1/2[1/4log₃27-1]+2+2
=1/2(3/4-1)+4
=-1/8+4
=31/4

(log9 4^更号27)/3+lg 20+log100 25+5^(log5 2)对数计算题(log9 4^更号27)/3+lg 20+log100 25+5^(log5 2)看不懂再Hi我 现场等
log9 3+log9 27=怎么求~
化简 根号 (3^(2log9((lgx)^2)-4lg根号x-loga(1/a))
log4(3)*log9(2)+log2(4倍根号下64) log9(32)*log64(2log4(3)*log9(2)+log2(4倍根号下64) log9(32)*log64(27)+log9(2)*log4(根27)
log3(5)+log9(5)求大神帮助log3(5)+log9(5)具体步骤,和,lg平方3-lg9+1配方
计算:(1/4)^log4^1/3-lg25-lg4-log9^27
(lgx)^2-lg x^2-3=0 求x (2)log9 27=?(3)log3(log4 64)=?(4)log(2+根号3) (2-根号3)
(1+1/2log9-lg240)/(1-2/3lg27+lg(36/5))+1=?
不等式log9(27^x-2*3^x)
不等式log9(27^x-2*3^x)
计算log8^3乘以log9^4
(log2^3 +log3^5) x ( log3^5 +log9^5 ) x lg 2 ,本人对数特别差,最好带解说,(log2^3 +log5^3) x ( log3^5 +log9^5 ) x lg 2
log√3^9+log9^27+(1/4)log4^1/16
log√3^9+log9^27+(1/4)log4^1/16
怎们算log9 27?
log9^27=
log9 27等于多少
