Answer:
A rational number is defined as the number that can be expressed in the form of a quotient or division of two integers. Both the numbers cannot be represented in the form of a rational number and have a non terminating non-repeating decimal trail. Thus, the square root of 17 is irrational.
This is non-terminating and the decimal part has no repeating pattern. So it is NOT a rational number. Hence, √20 is an irrational number.
Is the Square Root of 9 a Rational or an Irrational Number? If a number can be expressed in the form p/q, then it is a rational number. √9 = ±3 can be written in the form of a fraction 3/1. It proves that √9 is a rational number.
Hence, the square root of 8 is not a rational number. It is an irrational number.
Step-by-step explanation:
the answer is c. √9
√9 is rational
