Find the exact value of log base pi (pi^3 cos(pi)) I first canceled out log base pi and pi and was left with 3 cos (pi). Then I looked at the unit circle and looked at pi and cos is -1. So then I multiplied 3(-1)=-3 and my answer was wrong. Can someone explain what I am doing wrong please?

    I can't see where a pi would come from.
