Root 15 is irrational because root 15 can be expressed a to the whole root of (3*5) which can be expressed as root 3 *root 5 ,neither of their roots are rational.Therefore if we multiply irrational with another irrational number (which is not the same number) the product is irrational. Hence root 15 is irrational
