Irrational. 151 is not a perfect square (144 is the nearest one). square root of 151 is 12.288.
Yes. Irrational numbers are found by getting the square root of a negative number.
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.
Since it is the square root of a negative number, it is actually imaginary, neither rational nor irrational. It is equal to 9i, or 9 times whatever the square root of negative one is.square root of -81 = square root of 81 times i = 9i
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- integers are a kind of rational number and are not irrational. One well-known example of an irrational number is the square root of 2.
The square root of 100 is 10, and it is a rational number.
Yes, they are rational.
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.
Some irrational numbers are square roots, but not every one. Not every square root is irrational.
yes, one such is the square root of four, which is two
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.
