(a). This question was attractive to most candidates and they did very well.
(b). The case here was different as many candidates exhibited lack of the
knowledge of laws of logarithms.
The numerator = log 64 x 4 = log16 or 4log2
16
The denominator = log 32 or 5 log 2
Thus, the expression simplifies to 4log2 = 4/5
5log2
Some candidates applied Laws of logarithm here to get 4log2 – 5log2 which is wrong.
