The square root of 18 is: ± 4.242641
No. √324 = 18 = 18/1 = a rational number.
NO!! Irrational Numbers are those where the decimal digits go to infinity AND there is no regular order in the decimal digits. pi = 3.141592.... is the most well known irrational number. as are the 'Square roots' od prime numbers;-# sqrt(2) = 1.414213.... sqrt(3) = 1.73205... sqrt(5) = 2.23606... However, such as numbers as 3.3333..... is NOT irrational, because the decimals are in regular order. Similarly 2.373737.... or 5 .678678678.... Are NOT irrational because the decimals are in a regular order. NB '....''' at the end of a decimal is the mathematical indication of recurring to infinity.
Yes it's a real number but it is an irrational number because it can't be expressed as a fraction.
120 over 18 as a mixed number = 62/3
It is neither because the square root of -18 is an imaginary number but the square root of 18 is irrational
Integers (whole numbers, without a decimal point, including negative whole numbers) are real numbers; they are rational; therefore they are not irrational.

The square root of 18 is an irrational number because it cannot be expressed as a fraction.
Yes
It is a rational number
No. An irrational number cannot be expressed as a/b where a and b are integers, b not zero. 18 = 18/1 = 36/2 = -36/-2 etc.
No. √324 = 18 = 18/1 = a rational number.
-18 is the ratio of -18 and 1 ... nice and rational. Also the ratio of 18 and -1, of 36 and -2, of 180 and -10, etc.
irrational
18 and 20
If an even number of negative factors are multiplied together (such as 18 factors), the answer will be positive. If there are an odd number of negative factors, the answer will be negative.
