Answer:

3-✓5 is an irrational number.

Step-by-step explanation:

let, 3-✓5 = p/q [where p and q are co-prime no.]

✓5 = p/q+3

We know that ✓5 is a irrational number but p/q-3 is a rational number.

We also know that irrational number is not equal to rational number. Therefore we say that 3-✓5 is a irrational number.
