PhysChemTutor's answer to Zwen's Secondary 4 A Maths Singapore question.
I did change base to do. But it was getting me nowhere.
That's why i skip steps. So hopefully you follow the method and at the same time think hard.

Where are this questions from? Poly modules?
Yes, poly math module. I'm dying here because I did not take A math in secondary school. All these log stuff very new to me.
No wonder. Ok you go try first, if really cannot then I'll type a working later
