Unfamiliar integral.

Calculus Level 5

If the integral Φ ( n , k , m , r , p ) = 0 1 ( ln x n ! ln x k ! ln x m 2 ln x r 2 ln x p ! ) d x \Phi(n,k,m,r,p)=\int_0^1\left(\frac{\ln x^{-n!}\cdot \ln x^{-k!}}{\ln x^{-m^2} \cdot \ln x^{-r^2}\cdot \ln x^{-p!}}\right)^{dx} and m = 1 r = 1 m Φ ( 1 2 , 3 2 , m , r , 3 4 ) = Γ ( 1 b ) e γ a c π b d \sum_{m=1}^{\infty}\sum_{r=1}^{m}\Phi\left(\frac{1}{2},\frac{3}{2},m,r,\frac{3}{4}\right)=\frac{\Gamma\left(\frac{1}{b}\right) e^{\gamma}}{\sqrt{a}}\cdot \frac{c\pi^{b}}{d} where a , b , c a,b,c and d d are positive integers with g.c.d ( c , d ) = 1 \text{g.c.d}(c,d)=1 . Find the value of a + b + c + d a+b+c+d .
