The square root of 1 is 1 which is a rational number
Irrational. 151 is not a perfect square (144 is the nearest one). square root of 151 is 12.288.
One over sixteen = 1/16, which is a rational number (not irrational). The square root of 1/16 = 1/4 (or -1/4), which is also a rational, so the answer is No.
Yes. Irrational numbers are found by getting the square root of a negative number.
The square root of 40 is an irrational number, due to the fact that one could extend the answer to an infinite number of decimal places if one was able to.
no square root of 9 is 3 which is rational -- to be more specific: an irrational number is a number that cannot be expressed as a fraction. Pi, for example, is one of these numbers. If a number is not a perfect square (4, 16, 9, 144, 225, etc.), then it's square root is likely to be an irrational number. For example, the square root of 2 (1.41421356...) is an irrational number because it cannot accurately be expressed as a fraction.
A rational number is one that can be expressed as the ratio of two integers, for instance, 1/3, -5/3, 8 (which is equal to 8/1). An irrational number can't be expressed as the ratio of two integers. It has been proven that the square root of 2 (as well as the square root of any positive integer that is not a perfect square) is irrational. Pi and e, two important numbers in mathematics, are also irrational. It has also been proven that there are more irrational than rational numbers.
The square root of 100 is 10, and it is a rational number.
An example is the square root of a number. Ex: square root of 2. This is 1 example, not the main one. Any cube root or square root which doesn't give a perfect number is an irrational number. Ex; square root and cube root of 5, since their answer will be 2.24 and 1.70 which are not perfect numbers like square roots of 25 and 64 or cube roots of 27 and 216.
A rational number can be expressed as the ratio of two integers (the number one does not count). An irrational number cannot. The square root of 5 cannot be expressed as the quotient of two integers. This assertion is by experience that the square root of a prime number is irrational. There are several methods to prove the irrationality -- look for them elsewhere. For the sake of curiosity, my calculator gives the following result for it: 2.2360679774997896964091736687312762354406183596115257242708972454105209256378048994144144083787822749695081761507737835042532677244470738635863601215334527088667781731918791658112766453226398565805357613504175337850034233924140644420864325390972525926272288762995174024406816117759089094984923713907297288984820886415426898940991316935770197486788844250897541329561831769214999774248015304341150359576683325124988151781394080005624208552435422355561063063428202340933319829339597463522712013417496142026359047379... You can say that it is irrational by looking at the inexact answer.
Yes, they are rational.
an irrational number. also called a "surd". like 1+sqrt(5). (sqrt=square root)
yes, one such is the square root of four, which is two
