hi, masters !
look at this thing carefully :
1
2 3 4
5 6 7 8 9
10 11 12 13 14 15 16
17 18 19 20 .................
find the line and the column where the number 795471 will appear !
Given X=((√(√x))+(1/( (√(√x)))))^n .
What is the coefficient of x^(5−(n/4) ?)
propositions:
a. 5((n!)/(10!))
b. ((n!)/(5!))
c. ((n),((10)) )
d. ((n),(5) )
Let α≠1 and α^(13) =1. If a=α+α^3 +α^4 +α^(−4) +α^(−3) +
α^(−1) and b=α^2 +α^5 +α^6 +α^(−6) +α^(−5) +α^(−2) then the
quadratic equation whose roots are a and b is
(A) x^2 +x+3=0 (B) x^2 +x+4=0
(C) x^2 +x−3=0 (D) x^2 +x−4=0
