Find all natural numbers x > 1 for which x^2 - 3 is divisible by x-1
choli [55]

Answer: x = { 2 ; 3 }

+) x² - 3 = x² - 1 - 2 = (x - 1)(x + 1) - 2

+) x² - 3 is divisible by x-1 but (x -1)(x + 1) is divisible by x-1

=> 2 must be divisible by x-1

=> x - 1 is divisor of 2

=> (x - 1) ∈ {-1; 1; 2; - 2;}

but x > 1 => x - 1 > 0

⇒ x - 1 = {1; 2; }

+) with x - 1 = 1 => x = 2

           x - 1 = 2 => x = 3

katen-ka-za [31]
Change the dimensions of the right rectangular prism to improper-like fractions. The dimensions are 9/4, 2/4, and 4/4 inches.

To find the volume of this right rectangular prism, fill it with ¼ inch cubes. It takes 64 – ¼ inch cubes to fill one unit cube.

The right rectangular prism can be filled with ¼ inch cubes. It takes 9 x 2 x 4 cubes to fill this right rectangular prism. It takes 72 – ¼ inch cubes to fill this right rectangular prism.

The volume of the right rectangular prism is 9/4 x 2/4 x 4/4 = 72/64 or 1 8/64 or 1 1/8 cubic inches.
