-root(2.25) is rational or irrational???
sqrt [ 225/100] = 15/10 which is rational
Ah, just like the one Bosnian just answered for you :(
To determine whether the square root of 2.25 is rational or irrational, we first need to understand what these terms mean.
A rational number is any number that can be expressed as a fraction (ratio) of two integers, where the denominator is not zero. Irrational numbers, on the other hand, cannot be expressed as a fraction and have decimal representations that never terminate or repeat.
In this case, we are considering the square root of 2.25. The square root (√) of a number is a value that, when multiplied by itself, gives the original number.
To find the square root of 2.25, we can use a calculator or a mathematical method called estimation. Using a calculator, we find that √2.25 is equal to 1.5.
Now, let's analyze 1.5. Since we obtained the square root of 2.25 as a decimal value without repeating or terminating, it cannot be expressed as a fraction. Therefore, the square root of 2.25 is an example of an irrational number.
In conclusion, the square root of 2.25 is an irrational number.
