Question: If A = 2, B = 4, C = 6, D = 8, E = 10 and so on, what is the meaning of following number 40, 18, 14, 10, 36
Solution:
Given,
A = 2, B = 4, C = 6, D = 8, E = 10.......
∴ Each code = Letter position × 2
So
40 ÷ 2 = 20 → T
18 ÷ 2 = 9 → I
14 ÷ 2 = 7 → G
10 ÷ 2 = 5 → E
36 ÷ 2 = 18 → R
the meaning of following number = TIGER

প্রশ্ন: t + 1/t = 2 হলে t5 - 1/t5 = ?
সমাধান:
দেওয়া আছে,
t + 1/t = 2
বা, t2 + 1 = 2t
বা, t2 - 2t + 1 = 0
বা, (t - 1)2 = 0
বা, t - 1 = 0
∴ t = 1
∴ t5 - 1/t5
= 1 - 1/1
= 1 - 1
= 0

প্রশ্ন: f(x) = x3 - mx2 + 7x - 10 হয়, তাহলে m এর কোন মানের জন্য f(2) = 0 হবে?
সমাধান:
দেওয়া আছে,
f(x) = x3 - mx2 + 7x - 10
= (2)3 - m(2)2 + 7(2) - 10
= 8 - 4m + 14 - 10
= 12 - 4m
এখন,
f(2) = 0
⇒ 12 - 4m = 0
⇒ 4m = 12
∴ m = 3

প্রশ্ন: x - 1/x = 1 হলে x3 - 1/x3 এর মান কত?
সমাধান:
x - 1/x = 1
x3 - 1/x3 = (x - 1/x)3 + 3.x .1/x.(x - 1/x)
= 13 + 3 . 1
= 1 + 3
= 4
