According to the logarithmic property of the base change, the corrected answer is option one or the first. The logarithmic property of base change given that logx (b) = logc (b) / logc (x) Therefore, the same property applies to this problem and the correct expression for this question is: y1 = log (x + 3) / log 4 y2 = log (2 + x) / log2
