Pls to solve i don't know what is answer

2020

Step-by-step explanation:

This is an example of what is called an "infinite continued fraction".

For the repeated fraction:

y = 2019 / (2 + 2019 / (2 + 2019 / (2 + 2019 / ...

We can rewrite using substitution:

y = 2019 / (2 + y)

Solving for y:

y (2 + y) = 2019

2y + y² = 2019

y² + 2y + 1 = 2020

(y + 1)² = 2020

y + 1 = ±√2020

y = -1 ± √2020

Since the repeated fraction must be positive, y = -1 + √2020.

Therefore:

x = (1 + y)²

x = (1 + -1 + √2020)²

x = 2020
