Q. If a+1/a =p, then the value of a^3+(1/a)^3=..?

Ans: p^3-3p
Exp...
a^3+b^3=(a+b)-3.a.b(a+b) [formula]
Then,
a^3+(1/a)^3
= (a+1/a)^3 -3.a.1/a (a+1/a)
=P^3-3.1.1.p (putting value)
=P^3-3p
Similarly a^2+(1/a)^2= p^-2

Summation of any arithmetic series = n{2a+(n-1)d}/2 or n(a+l)/2,Where n= Count of the series. a=first element of the series, d= Common difference i.e. difference between consecutive two elements of the series, l= Last element of the series. For example sum of the series 1+3+5.....+21 = ?
Here a=1, n=11, d=2 and l= 21 so sum= 11{2*1+(11-1)*2}/2=121 or sum=11(21+1)/2= 121

Note: Gauss is the famous mathematician associated with finding the sum of the first 100 natural numbers.
