So, it was the assumption that √2 was a rational number that got us into trouble, so that …
WebThe roots of polynomials, such as ax 3 + bx 2 + cx + d = 0, with integer (or rational) coefficients. Algebraic numbers may be real, imaginary, or complex. For example, the roots of x 2 − 2 = 0 are ±√2, the roots of x 2 + 4 = 0 are ±2i, and the roots of … WebWhich of the following are related? (a) 3 and 4/5 (b) 1 + 5 and 1 − 5 (c) 2 and 2 + 1 (d) 2 and 3 (e) 2 1 and 2 2 − 1 10. If a is a positive rational number, let a ~ = 1 + a 2 + a . Prove that a ˉ 2 is closer to 2 then a 2 is. By starting with a = 1, use this to find a sequence of rational numbers approximating 2 . 11.
WebA rational number is a number that can be express as the ratio of two integers. A number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever). However, one third can be express as 1 divided by 3, and since 1 and 3 are both integers, one third is a rational number.
