log(8)(9)+log(27)(32)求过程拜托各位大神
如题
log(8)(9)+log(27)(32)求过程拜托各位大神如题
log8(9)=ln9/ln8=(2ln3)/(3ln2) log27(32)=ln32/ln27=(5ln2)/(3ln3) 所以 log8(9)*log27(32)=(2ln3)/(3ln2)*(5ln2)/(3ln3)=10/9
log[8,9]=log[2^3,3^2]=2/3*log[2,3] log[27,32]=log[3^3,2^5]=5/3*log[3,2]=5/(3log[2,3]) 相乘可以再算下去得10/9,相加就只能算到上面两式相加为止了
log(8)9-log(27)32的值,
求log(8)9-log(27)32的值,
log(16) 9*log(27) 32=?
(log(8)9)/log(2)3
求值 log【9(下标)】3+log【 9(下标)】27 log【2】(1/2)- log【1/2】2
化简(log[4]3+log[8]3)×(log[3]2+log[9]2)如题
(LOG(3,4)+LOG(3,8))(LOG(2,3)+LOG(2,9))等于几 看的懂吧
高一函数【运算对数】运算:(log【2】3-log【4】27)×(log【3】4+log【9】8)【 】内的是底数.
对数计算1.{log(4)(3)+ log(8) (3)} X {log(3)(2)+log(9)(2)}2.{log(2)(3)} X {log(3)(4)+log(9)(2)}3.(lg2)^+1g2X 1g5 +1g50
求值;log(8)9乘log(3)32-lg5-lg2+lne的平方=
log(x+5)=log(x)+log(2) log(8)+log(x)=log(24) 2log(x)=log(2x)+log(3)

化简2log`5(10)+log`3(0.25)+log`1/5(125)=(2) log`2(根号2)+log`9(27)+(1/4)^log`4(1/16) 注意 `为下角标
log(27)32 × log(64)27+log(9)2 × log(4)根号27=?log(27)32 × log(64)27+log(9)2 × log(4)根号27=?
求值 log(2)9×log(3)2
求值,(log(6)4+log(6)9)^2
如何计算啊.(log底数4真数3+log底数8真数3)乘(log底数3真数2+log底数9真数2)=?
问道数学题(高一)(对数)化简:(log 3 + log 3)(log 2 + log 2) 4 8 3 9有些过程,拜托了.
