" Value of the "D=|[a^(3)-x,a^(4)-x,a^(5)-x],[a^(5)-x,a^(6)-x,a^(7)-x],[a^(7)-x,a^(8)-x,a^(9)-x]|" is "

If f(x)=x^(9)-6x^(8)-2x^(7)+12x^(6)+x^(4)-7x^(3)+6x^(2)+x-3, find f(6)

If f(x)=x^(9)-6x^(8)-2x^(7)+12x^(6)+x^(4)-7x^(3)+6x^(2)+x-3 find f(6)

If (x)=x^(9)-6x^(8)-2x^(7)+12x^(6)+x^(4)-7x^(3)+6x^(2)+x-3 find f(6) .

If x,y,z in R , then the value of determinant |((5^(x)+5^(-x))^(2) , (5^(x)-5^(-x))^(2),1),((6^(x)+6^(-x))^(2),(6^(x)-6^(-x))^(2), 1),((7^(x)+7^(-x))^(2),(7^(x)-7^(-x))^(2),1)| is

Subtract: 7x^(4)-5x^(3)+4x^(2)+3x-3 from 6x^(4)-4x^(3)-8x^(2)-2x+7

Evaluate lim_(x to sqrt(3)) (3x^(8) + x^(7) - 11x^(6) - 2x^(5) - 9x^(4) - x^(3) + 35x^(2) + 6x + 30)/(x^(5) - 2x^(4) + 4x^(2) - 9x + 6)

simplify (x+x^(2)+x^(3)+x^(4)+x^(5)+x^(6)+x^(7))/(x^(-3)+x^(-4)+x^(-5)+x^(-6)+x^(-7)+x^(-8)+x^(-9))

If f(x)=x^(9)-6x^(8)-2x^(7)+12x^(6)+x^(4)-7x^(3)+6x^(2)+x-3 , then find the value of f(6).
