Solution

The correct option is D More than 2

We have,

1log3π+1log4π

We know that

logax=logexlogea

Therefore,

=1logeπloge3+1logeπloge4

=loge3logeπ+loge4logeπ

=loge3+loge4logeπ

We know that

logem+logen=loge(mn)

Therefore,

=loge12logeπ

=2.4841.144

=2.17

Hence, the value is more than 2.
