Answer:
64 & 81
Step-by-step explanation:
Since 8 x 9 = 72, let's try 8 x 8 and 9 x 9 and see if they result in the 2 perfect squares on either side of 72.
8 x 8 = 64, lower than 72, so, correct.
9 x 9= 81, higher than 72, so, correct.
ANSWER: 72 lies between the perfect squares 64 and 81.
I'm always happy to help :)
