Question
The irrational number between 2 and 2.5 isa. √11 b. √5 c. √22.5 d. √12.5
Solution
The irrational number between 2 and 2.5 is b. √5.
Here's why:
The square root of a number is a value that, when multiplied by itself, gives the original number.
The square root of 4 is 2, and the square root of 9 is 3. Therefore, the square root of any number between 4 and 9 will be between 2 and 3.
5 is between 4 and 9, so its square root (√5) will be between 2 and 3.
Therefore, √5 is the only option that is an irrational number between 2 and 2.5.
