⁴log 7 = p
log 7 / log 4 = p
log 7 / log 2² = p
log 7 / 2 log 2 = p
²log 7 / 2 ²log 2 = p
²log 7 = 2p
⁵log 3 = q
³log 5 = 1/q

a). ²log 49 = ²log 7² = 2 ²log7 = 2. 2p = 4p
b). ⁸log 1/7 = ⁸log 7⁻¹
= log 7⁻¹ / log 2³
= -1/3 (log 7 / log 2)
= -1/3 ²log 7
= -1/3 (2p)
= -2p/3
c). ¹⁵log 9 = log 9 / log 15
= log 3² / log 3.5
= 2 ³log 3 / ³log 5 + ³log 3
= 2.1 / ³log5 +1
= 2 / ((1/q) +1)
= 2q / (1+q)
