                                        Dear student,
The general term of the series can be given by:
T_{n}=\frac{n^{5}\left ( n+1 \right )^{7}}{n!}

So, the required sum can be found as:
S_{n}=\sum_{1}^{\infty}T_{n}=\sum_{1}^{\infty}\frac{n^{5}\left ( n+1 \right )^{7}}{n!}
Using the standard formulae, the required sum can be found.

​Q . TOTAL NUMBER OF SOLUTIONS OF - 2 X + 3 X + 4 X – 5 X = 0 IS=?
 
 
. when x tends to – infinity the value of expression tends to zero. But we cant say – infinity is a root of equation as – infinity is not any fixed no.

The number of points (x,y) (where x and y both are perfect squares of integers) on the parabola y^2=px,p being a prime number, is ?
 
 
y 2 = px y = sqrt(px) Since x & y are perfect square integers, sqrt(x) is an integer. Since p is a prime no., sqrt(p) is an irrational no. The point which satisfies the given condition is...
