"The square root of 12 is between 4 & 5."

Step-by-step explanation:

1. "The square root of 12 is between 4 & 5" This doesn't make sense: 4 squared is 16 and 5 squared is 25. 12 is not between either of those numbers.

2. "The square root of 90 is between 9 & 10." 9 squared is 81, 10 squared is 100. 90 is between those numbers, so this makes sense.

3. "The square root of 40 is between 6 & 7." 6 squared is 36, and 7 squared is 49. 40 is between these numbers, so that makes sense.

4. "The square root of 5 is between 2 & 3." 2 squared is 4, and 3 squared is 9. 5 is between those two numbers, so this makes sense.

Therefore, the statement that is not true is the first one: "The square root of 12 is between 4 & 5."

I hope this helps!
