There are no rational numbers between sqrt(-26) and sqrt(-15). The interval comprises purely imaginary numbers.
The square root of 225 is 15, which is NOT an irrational number.
Look for square numbers that are factors of 540, like 36. The square root of 540 = 6 times the square root of 15.

The square root of 225 is 15, which is NOT an irrational number.
Two times the square root of 15 is the square root of 60. This is not a perfect square so we can only approximate it. It is about 7.75. Numbers such as 2 times the square root of 15 are known as irrational numbers since they cannot be written as a ratio or fraction.
Look for square numbers that are factors of 540, like 36. The square root of 540 = 6 times the square root of 15.
The numbers are: 8 times square root of 15 and 8 times the square of 15
There are none but: (15+square root of 129)/2 and (15-square root of 129)/2 will give a sum of 15 and a product of 24
