Let (x,y,z) be an arbitrary point lying on a plane P which passes through the points (42,0,0), (0,42,0) and (0,0,42), then the value of the expression 3+(x-11)/((y-19)^(2)(z-12)^(2))+(y-19)/((x-11)^(2)(z-12)^(2))+(z-12)/((x-11)^(2)(y-19)^(2))-(x+y+z)/(14(x-11)(y-19)(z-12)) is equal to :

यदि 25 ^(-2x) = ( 5 ^((48)/(2)))/(5 ^((26)/(2)). 25 ^((19)/(2)) है तब x = ?
