Not necessarily. The square root of 2.56 equals 1.6, and the square root of 0.25 equals 0.5, for two examples. If the decimal represents a rational number that is a fraction of two perfect squares, then the square root will be a rational number. The two examples I gave were 2.56 = 256/100, and 0.25 = 1/4.
The square root of 72 is an irrational number. Since 72 is not a perfect square, the decimal is endless. (just like the value of pi)
Yes.
No. The square root of two is an irrational number. If you multiply the square root of two by the square root of two, you get two which is a rational number.
-612
It is an irrational number and it is about 3.4746 rounded to 4 decimal places
The square of a rational number can be either rational or irrational. However, the square of an irrational number is always irrational.
It is an irrational number and as a decimal number it has no ending
yes, it is irrational. An irrational number can defined as a number that can not be expressed as a finite nor a repeating decimal.
No
The square root of 72 is an irrational number. Since 72 is not a perfect square, the decimal is endless. (just like the value of pi)
No. It could be square or division problem too.
The square root of 15 is an irrational number and it is about 3.873 rounded to three decimal places
The square root of 6 is an irrational number; it can only be approximated as a decimal. √6 ≈ 2.449
Yes the square root of 150 is 12.247448713915890490986420373529This is irrational because the answer is a number that the decimal goes on forever without repeating.
Yes.
The square root of 257 is an irrational number, as it cannot be expressed as a fraction or whole number. It is a non-repeating, non-terminating decimal.
The square root of 2 is irrational, yet the product of it with itself is 2. So the answer is no.
