let x1 x2 xn be n real numbers let x x1 x2 xnn be their average use a proof by contradiction to prove that at least one of x1 x2 xn is greater than or equal to x 44785

Use a proof by contradiction to show that there is no rational number r for which r^3 r 1=0. [Hint: Assume that r=a / b is a root, where a and b are integers and a / b is in lowest terms. Obtain an equation involving integers by multiplying by b^3. Then look at whether a and b are each odd or even.] | Numerade
