Given that x + 1 / x = 4, find the value of cube of X + 1 / 3 of X?

x³+1/x³=(x+1/x)(x²-1+1/x²)=(x+1/x)[(x+1/x)²-3]=4×(4²-3)=42

Given that the absolute value of X is 3 and Y is the reciprocal of - 1 / 2, find the value of cube of X + cube of Y

Because | x | = 3
So x = ± 3
And because
Y is the reciprocal of - 1 / 2
So y = - 2
So X3 + Y3 = 27-8 or - 27-8
=19 or - 35

Known: the square of x-5x-1 = 0, find the cube of {X-2} - {X-1} + 1 of the square of X-2

(x-2)^3-(x-1)+1
=[(x-2)+1]*[(x-2)^2-(x-2)+1]-(x-1)
=(x-1)*(x^2-5X+7)-(x-1)
=(x-1)*(x^2-5x+6) .x^2-5x-1+7=7
=7(x-1)
(x-2)^2=x^2-4x+4=x^2-5x-1+x+5=x+5

Given that x squared plus x minus 3 is equal to 0, then find the value of x minus 1 / 3 minus x squared minus x cube

X ^ 2 + x-3 = 0 to get x + x ^ 2 = 3
X minus 1 / 3 minus x square minus x cube
=x(1-x^2)/x-1
=-x-x^2
=-(x+x^2)
=-3
