Weekly Math Problem #50

Limits. For the most part, I understand limits. It reminds me of integration...where I get the idea but most of the work is knowing the techniques and when to implement them. Such is limits. There are different techniques and knowing when to implement them is important...well...it's important in math. If you're not into math, you most likely don't care. 🤷🏿‍♀️

To solve this week's problem in completion, you need to recall the following math skills:

        ✔️     How to find limits involving radical expressions

Just when you think you have it all figured out...you don't, sometimes. 😩 Let's get into this solution. 

The first thing I did was substitute -1 into the expression to see if a value pops out...but I was met with an indeterminate form.

 

The indeterminate form doesn't help me so, I tried another method--rationalizing the numerator--to see if that would help me with substitution.

With the rationalized form of the expression, I tried substitution again.

Lo and behold...indeterminate form again. 😩 Now, I need another method. This one, I know, won't fail me--L'Hôpital's Rule.

Ahhh...an answer, finally! All of that work to come up with 1/6. 😅🤷🏿‍♀️
