Given:
Given the numbers
[tex]\sqrt{64}\text{ and }\frac{1}{4}[/tex]Required: Identify rational or irrational
Explanation:
A rational number is a real number of the form p/q, where p and q are integers.
The real number which can not be in the form p/q are real numbers.
14. The number
[tex]\sqrt{64}=8[/tex]which is same as 8/1. So, it is a rational number.
15. 1/4 is of the form p/q with p = 1 and q = 4. So, the fraction 1/4 is a rational number.
Final Answer:
[tex]\begin{gathered} 14.\text{ }\sqrt{64}\text{ is a rational number.} \\ 15.\frac{1}{4}\text{ is a rational number} \end{gathered}[/tex]
