How many times does Squareroo take the square root if the number entered into it is 660? I tried this problem and I got 5, but I don't know if I'm right or if my work is right, so any answers will be greatly appreciated.

Thanks so mych (1) $$676 = 26^2$$ is the perfect square closest to $$660$$. (2) The square root of the perfect square $$676$$ is $$26$$. (3) $$25 = 5^2$$is the perfect square closest to $$26$$. (4) The square root of the perfect square $$25$$ is $$5$$. (5) $$4 = 2^2$$ is the perfect square closest to $$5$$. (6) The square root of the perfect square $$4$$ is $$2$$. (7) $$1 = 1^2$$ is the perfect square closest to $$2$$. (8) The square root of the perfect square $$1$$ is $$1$$. Squareroo took the square root from the above $$4$$ time at step (2), (4), (6) and (8). My answer is $$4$$. _________________ MathRevolution: Finish GMAT Quant Section with 10 minutes to spare The one-and-only World’s First Variable Approach for DS and IVY Approach for PS with ease, speed and accuracy.
