`If |[3,x,2],[1,4,x],[5,x+8,2]|=0, then the value of x is `

If |[x,1],[1,x]|=|[2,0],[8,4]| then value of x is :

If |{:(2,3,2),(x,x,x),(4,9,1):}|+3=0 then the value of x is

If |(x,2,3),(2,3,x),(3,x,2)|=|(1,x,4),(x,4,1),(4,1,x)|=|(0,5,x),(5,x,0),(x,0,5)|=0, then the value of x equals (x in R):

If |[1, x, x^2], [x, x^2, 1], [x^2, 1, x]|=3, then find the value of |[x^3-1, 0, x-x^4], [0, x-x^4, x^3-1], [x-x^4, x^3-1, 0]|

If the mean of x_(1),x_(2) is 7.5 and the mean of x_(1),x_(2),x_(3) is 8, then the value of x_(3) is

If (2x4)(x-8)=0 , find the positive value of x

If x^2+x+1 is a factor of the polynomial 3x^3+8x^2+8x+3+5k , then the value of k is (a) 0 (b) 2/5 (c) 5/2 (d) -1

If f(x) = (x - 1)(x - 2)(x - 3)(x - 4)(x - 5) , then the value of f' (5) is equal to

If f(x) = int(5x^(8)+7x^(6))/((x^(2)+1+2x^(7))^(2))dx, (x ge 0) , and f(0) = 0, then the value of f(1) is
