Answer:
yes
Step-by-step explanation:
Recall that a rational number is a number that results from dividing 2 integers
I'm not sure if your question refers to (√4) / 9 or √(4/9), but either way both are rational numbers:
If (√4) / 9, Then,
(√4) / 9
= 2/9
Since both 2 and 9 are integers, then 2/9 is a rational number
If √(4 / 9), Then,
√(4 / 9)
= √4 / √9
= 2/3
Since both 2 and 3 are integers, then 2/3 is also a rational number
