log46×log69×log94=
To solve this problem, we need to recognize that the expression log46×log69×log94 fits the identity of logarithms: logab×logbc×logca=1.
Let us examine the expression:
- The first term is log46, where a=4 and b=6.
- The second term is log69, where b=6 and c=9.
- The third term is log94, where c=9 and a=4.
Notice how log46, log69, and log94 correspond respectively to logab, logbc, and logca. Thus, the entire expression matches the multiplication identity of logarithms: logab×logbc×logca=1.
Therefore, the value of the expression log46×log69×log94 is 1.
