[P_(T),[x+9],[x,x+9],x=x],[x,x=x+4]=16(3x+9)

If |[x-2,2x-3,3x-4],[x-4,2x-9,3 x-16],[x-8,2x-27,3 x-64]|=0 then x=

Solve for x: |(x+9,x,x),(x,x+9,x),(x,x,x+9)|=0

If [[x,4],[9,x]]=[[6,4],[9,6]], then x is equal to:

3+4x=x+9

Solve for x |x-2 , 2x-3, 3x-4,x-4 ,2x-9, 3x-16 ,x-8, 2x-27, 3x-64|=0.

Find the value of x, if |(x-2,2x-3,3x-4),(x-4,2x-9,3x-16),(x-8,2x-27,3x-64)|=0 .

If p.m.f of a r.v.X is P(X)=P(A)=(4/x)(5/9)^x.(4/9)^(4-x) ,x=0,1,2,3,4 then E(X)=………….
