已知x满足等式log5[log3(log2x)]=0,求x的值如题
已知x满足等式log5[log3(log2x)]=0,求x的值
如题
已知x满足等式log5[log3(log2x)]=0,求x的值如题
log5[log3(log2x)]=0=log5(1)
所以log3(log2x)=1=loh3(3)
所以log2(x)=3
x=2³=8
log5[log3(log2x)]=0,则log3(log2x)=1,于是log2x=3,最后x=2的3次方=8
开第一层log5,得到:log3(log2x)=1
开第二层log3,得到:log2x=3
开第三层log2,得到:x=2^3=8
已知x满足等式log5[log3(log2x)]=0,求x的值如题
已知log5(log3(log2x))=1,求X
已知x满足等式log3^(log4^x)=0,求log1/2^x的值
log a 2+log a 2分之1log3 18-log3 22log5 25-3log2 64已知lg2=a lg3=b求下列各式的值1.lg6 2.log3 4 3.log2 12 4.lg2分之3已知X的对数,求X1.lgx=lga+lgb 2.loga x=loga m-loga n3.lgx=31gn-lgm 4.loga x=2分之1loga b-loga c呵呵 不好意思
log6(x)/log6(3)为什么等于log3(x)log3(x)/log3(5)为什么等于log5(x)
利用换底公式计算下面题目?log2 5 x log5 4 log2 3 x log3 4 x log4 5 x log5 6 x log6 7 x log7 8 (log后面数字为底数小一点)
已知log2=a,log3=b,用a、b表示log5 72 (急~)1.已知log2=a,log3=b,用a、b表示log5 722.已知x=log2 5,求2^x+4^-x
解对数方程 log3(x)=log5(x)
log5[log3(log2^x)]=1,x=
求满足等式log3^(x-1)=log9^(x+5)的x
已知log2[log4(log3x)]=log3[log5(log2y)]=0,求4更号x-y^1/5
已知log2[log4(log3x)]=log3[log5(log2y)]=0,求4更号x-y^1/5写过程
log3[log5(log2x)]=0 求x的值
若log2(x)=log3(y)=log5(z)
一道高一数学题对数log2,详见补充已知log2[log1/2(log2^x)]=log3[log1/3(log3^y)]=log5[log1/5(log5^z)]=0,试比较x,y,z的大小?
(1)求10^log10 3-10^log5 1+π^logπ 2的值(2)已知lg2=a,lg3=b,求log3 6的值(3)已知x+x^-1=4,求x+x^-2的值
已知a=log3(4),4^b=3,则log5(a)+log5(b)=?
计算log的题目2log5 10+2log5 0.5+log2 1+3log3 3log后为系数,特隔空格区分,
