WebThe square root of a given number is rational if and only if it is an integer, which is equivalent to the given number being a perfect square. A straightforward way to determine if a number is a perfect square is to derive its prime factorization. It is a perfect square if and only if the exponent of every prime in that factorization is even. WebTo decide if an integer is a rational number, we try to write it as a ratio of two integers. An easy way to do this is to write it as a fraction with denominator one. 3= 3 1, −8= −8 1, 0= 0 1 3 = 3 1, − 8 = − 8 1, 0 = 0 1. Since any integer can be written as the ratio of two integers, all integers are rational numbers.

How can you tell whether a square root of a whole number is rational …

WebFeb 19, 2024 · Here is how it works for the fraction 7 16: For the first step of the division, we ask how many 16’s are in 70. (Really, we are asking how many 1.6’s are in 7.0, but this is equivalent to asking how many 16’s are in 70). Since 16 × 4 = 64, we write a 4 above the 0 in 7.0. Then we subtract 64 from 70 and get 6 left over. WebJan 29, 2024 · At point x = 5 x = 5 the denominator is equal to zero, and this is undefined. Generally, a footnote is added to the expression that states y= 3 x−5 y = 3 x − 5, except when x = 5 x = 5. Then, at... northeast first aid
