\(\text{'Given that log2 = p and log3 = q, express log1.25 in terms of p and q.'}\)
{Are you sure you don't mean log1.5? Log1.5 → log(3/2) → log3 - log2 → q - p}
log1.25 → log(5/4) → log5 - log(2^2) → log(10/2) - 2log2 → log(10) - log2 - 2log2 → 1 - 3log2 → 1 - 3p. (Assuming log is log to base 10).
