# Do you even telescope?

Algebra Level 2

Find the value of the following sum:

$\sqrt{\frac{1}{1^3}}+\sqrt{\frac{1}{1^3+2^3}}+\sqrt{\frac{1}{1^3+2^3+3^3}}+\ldots \infty$

Note that $\infty$ here refers to the series having infinite terms and not the value $\infty$ in the sum! In other words, the sum continues indefinitely.

Inspired by this problem.
