(log3^14-log3^2)log7^9求值
(log3^14-log3^2)log7^9求值
(log3^14-log3^2)log7^9求值
2 ,log3^7log7^9=2
=log3 (14÷2) ×log7 9
=log3 7 ×2log7 3
=2
(log3^14-log3^2)log7^9求值
已知log7[log3(log2x)]=0,那么x1/2等于
log7[log3(log1/2x0]=0 求x
log3^27+lg25+lg4+7^log7^2+(-9.8)^0
解方程log7[log3(x)]=-1
log2^3*log3^7*log7^8
log3 18-log3 2=log3 16?
试证明:log7(2)/log7(3)=log3(2),其中7是底数,括号内的数字是真数
求值 3^2-log3(2)= log7(log5(log2(32)))=?
计算:log3底4次根号27/3+7^log7底2
log7[log3(log2x)]=0,则x的-1/2次方等于多少
已知log7[log3(log2x)]=0,那么x^-1/2=多少?
已知log7[log3(log2 x)]=0,求x^(-1/2)
已知log7【log3(log2 X)】=0,那么x^(-1/2)等于?
如果 log7[log3(log2^x)]=0 那么x^1/2等于没人答=.
已知log7[log3(log2∧x)]=0,那么x∧-1/2等于
若log7{log3(log1/2x)}=0,求x的值
log7[log3(log2x)]=0 那么X1/2次方等于多少
