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

Question: If cosA sinA = 0,then (cosA + sinA)2 =?
Solution:
(cosA + sinA)2
= cos2A + 2 cosA sinA + sin2A
= 1 + 2.0 [sin2A + cos2A = 1]
= 1 + 0
= 1

প্রশ্ন: logx(1/8) = - 2 হলে, x = কত?
সমাধান:
logx(1/8) = - 2
⇒ x- 2 = 1/8
⇒ 1/x2 = 1/8
⇒ x2 = (2√2)2
⇒ x = 2√2
