(9/64)^-1/2+logˇ1/3 3 是多少?
(9/64)^-1/2+logˇ1/3 3 是多少?
(9/64)^-1/2+logˇ1/3 3 是多少?
(9/64)^-1/2+logˇ1/3 3
=(64/9)^1/2-log(1/3)1/3
=8/3-1
=5/3
求值 log【9(下标)】3+log【 9(下标)】27 log【2】(1/2)- log【1/2】2
64^1/3-(-2/3)^0+log(2)8+(log(8)9)/(log(2)3)
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
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(3)3^1/2]^2+log(0.25)1/4+9log5根号5-log(根号3)1=?
已知lg2=0.301,lg3=0.477,求(1)log(2)1000,(2)log(5)0.5,(3)log(9)8,(4)log(1/2)1/3
(log(2)9+log(4)1/9)乘以(log(3)2+log(9)0.5) 括号里是底数.计算这道题.
2^log(4)(3)加3^log(9)(1/4)加5^log(1/25)(2)
log(2)1/25乘以log(3)1/8乘以log(5)1/9
log(2)(25)×log(3)(1/16)×log(5)(1/9)=?
计算:(1) log(2)(3)*log(3)(4)*log(4)(5)(2)log(2)(7)*log(√7)(8)
[log(4)3+log(8)3][log(3)2+log(9)2]-log(1/2)32∧1/4过程详细点,log(4)3是log以4为底3的对数,
log(2)5×log(5)81×log(3)4+In√e.还有(log(2)3+log(4)9)(log(3)4+1/2log(3)2)
1.求值25^log(5)^3+lg100+log(1/2)4.2.9^log(3)^5的值为( ).A.5 B.15 C.25 D.453.计算log(2)2+log(5)1-log(1/3)1/27+[3^log(3)5]^2+3^log(3)2.
(1)利用关系式log(a)N=ba^b=N证明换底公式 log(a)N=log(m)N/log(m)a (2)利用(1)中的换底公式求下式的值 log(2)25*log(3)4*log(5)9 (3)利用(1)中的换底公式证明 log(a)b*log(b)c*log(c)a=1
(1)利用关系式log(a)N=ba^b=N证明换底公式 log(a)N=log(m)N/log(m)a (2)利用(1)中的换底公式求下式的值 log(2)25*log(3)4*log(5)9 (3)利用(1)中的换底公式证明 log(a)b*log(b)c*log(c)a=1
证明对数运算法则(1)log(a)(MN)=log(a)(M)+log(a)(N); (2)log(a)(M/N)=log(a)(M)-log(a)(N);(1)log(a)(MN)=log(a)(M)+log(a)(N); (2)log(a)(M/N)=log(a)(M)-log(a)(N); (3)log(a)(M^n)=nlog(a)(M) (n∈R)
