求值 3^2-log3(2)= log7(log5(log2(32)))=?
求值 3^2-log3(2)= log7(log5(log2(32)))=?
求值 3^2-log3(2)= log7(log5(log2(32)))=?
3^2-log3(2)=
=3^2/3^(log3(2))
=9/2
log7(log5(log2(32)))
=log7(log5(5))
=log7 (1)
=0
(log3^14-log3^2)log7^9求值
求值 3^2-log3(2)= log7(log5(log2(32)))=?
试证明：log7（2）/log7（3)=log3(2),其中7是底数,括号内的数字是真数
已知log7[log3(log2x)]=0,那么x1/2等于
