- TL;DR Summary
- How t-substitutions can be determined for any given limits involving radicals?

Hello all,

Given following limits:

I was curious, how such t-substitution (letting x with t) can be determined?

Given following limits:

- ##\lim_{x \rightarrow 1} {\frac {\sqrt x -1} {x^2 - 1}}##
- ##\lim_{x \rightarrow 1} {\frac {\sqrt {x+1} - 2} {x - 3}}##
- ##\lim_{x \rightarrow 1} {\frac {\sqrt[3] x - \sqrt[4] x} {\sqrt[6] x - \sqrt x}}##

I was curious, how such t-substitution (letting x with t) can be determined?
