I just watched this video and I kept wondering, is there any easy way to calculate a fractional power.

This lesson uses the example of 4096^(1/3) which is the same as the square root, but it gives no examples of how to calculate this.

When I search online for examples, they all say to use the root to calculate the fractional power.

I understand the concept, and in the video it’s stated that sometimes you just need to do some guesswork to get where you need to be, but I wish there was a more clearer way of solving this rather than substituting one problem for another.
