If the roots `x^5-40 x^4+P x^3+Q x^2+R x+S=0` are n G.P. and the sum of their reciprocals is 10, then `|S|` is `4` b. `6` c. `8` d. none of these

If the roots of x^(5) - 40 x^(4) + Px^(3) + Qx^(2) + Rx + S = 0 are in G.P. and sum of their reciprocals is 10, then |S| is equal to

All roots of equation x ^(5) -40 x ^(4) + alphax ^(3) + beta x ^(2) + gamma x + delta =0 are in G.P. if the sum of their reciprocals is 10, then delta can be equal to :

The roots of the equation x^(5)-40x^(4)+ax^3+bx^2+cx+d=0 are in G.P. If sum of reciprocals of the roots is 10, then

If the roots of x^(4)+5x^(3)-30x^(2)-40x+64=0 are in G.P.,then the roots are

If the roots of the equation x^5-40x^(4)-px^(3)+Qx^2-Rx-S=0 are in geometric progression and the sum of the reciprocals of the roots is 10,then |S|=

For the equation |x^(2)|+|x|-6=0, the sum of the real roots is 1( b) 0(c)2 (d) none of these
