Answer:
irrational
Step-by-step explanation:
7 is not a square integer, so √7 is irrational.
When combined with rational numbers, the result will be irrational. Here, "combined" means √7 is multiplied by a rational number and the result subtracted from a rational number. Neither of those operations will give a rational result.
