Write an irrational number that can be added to the irrational number the square root of 15 to get a rational sum of 2

Step-by-step explanation:

if u is an irrational number added to a rational number (sqrt 15) to yield 2, then that would mean u would = root -1.78

which means you wouldn't have a real solution. if you want a complex answer, it would be sqrt(1.78)i

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
