Witryna14 lut 2014 · The main point is: The cube root of a natural number is rational iff it is infact an integer. More generally, any rational root of a monic polynomial with integer coefficients (such as X 3 − n) is in fact integer. So if n 3 is rational then n is a cube (and cannot be prime). Hint Any rational root of x 3 − p is an integer, by the Rational ... WitrynaFind the root of the following 121 a. 164 b.vo c. 2.25 d. 2.

Witryna√ (1/200) = √ (1)/√ (200) Simplify both square roots. √ (1) = 1 √ (200) = √ (10*10*2) = 10√ (2) So, your fraction becomes: 1/ [10√ (2)] Next, a simplified radical will have no radicals in the denominator. So you need to rationalize the denominator. 1/ [10√ (2)] = 1/ [10√ (2)] * √ (2)/√ (2) = √ (2)/ [10√ (4)] WitrynaFirstly: 16 = 2×2×2×2 = 2 4, and 90 = 2×3×3×5 = 2×3 2 ×5. ( 16 90) 2 = ( 24 2×32×5) 2. = ( 23 32×5) 2. = 26 34×52. But one thing becomes obvious: every exponent is an even … Witryna9. Between which two integers does the square root of 130 lie.
