উত্তরের বিবরণ
সমাধান:
loga(b4) = 4c
⇒ 4 × loga(b) = 4c [logn(mk) = k logn(m)]
⇒ loga(b) = c
আবার,
logb(a4) = 4d
⇒ 4 × logb(a) = 4d
⇒ logb(a) = d
∴ cd = loga(b) × logb(a)
⇒ cd = 1 ;[logn(m) × logm(n) = 1]

প্রশ্ন: log2 log√ee2 = ?
সমাধান:
log2 log√ee2
= log2 log√e(√e)4
= log2 (4 log√e√e)
= log2 (4 × 1)
= log2 4
= log2 22
= 2 log2 2
= 2 × 1
= 2
