Answer:
√16 and 8.070070007 are both rational
Step-by-step explanation:
√16 = 4 which is rational.
√7 = not a perfect squared root, so it's irrational.
813.1 = doesn't repeat or do anything sus so this number is rational.
-9 = this one is good. (The fact that it is negative doesn't matter)
8.070070007... = the 3 dots means it repeats forver, which makes it irational.
