Question:
i have a question about how to do double square roots with variables and powers.

example : v/"" v/"" 81y⁸

You can take the squarre roots in succession. In your example the Sqrt(81) is 9 and Sqrt(y⁸) is y⁴ so Sqrt(81 y⁸) is 9 y⁴.

Now apply the second square root operation. Sqrt(9) = 3 and Sqrt(y⁴) = y². Thus Sqrt(9 y⁴) = 3 y².

Thus
