Cracking the Code: Simplifying √108 Made Easy

Imagine staring at the square root of 108, feeling that familiar knot of anxiety tightening in your stomach. What if I told you that simplifying it can be as easy as pie? Okay, maybe not pie, but pretty close! If you’re gearing up for the Kaplan Nursing Entrance Exam, knowing how to tackle square roots like a pro can boost your confidence and sharpen your math skills. Let’s break it down like a math wizard so that you can wow your peers (and yourself) with your newfound skills.

So, first, take a deep breath. Ready? Let’s chat about how we’ll simplify √108. This involves a little trick called prime factorization, which sounds scary but is straightforward as long as we take it step by step. Think of it as finding the building blocks, the LEGO pieces, if you will, that make up 108. When we break it down, we find that 108 can be factored into 2 x 2 x 3 x 3 x 3. You can also write this in exponent form, like so: 2^2 x 3^3.

Now, let’s take a moment here. Why do we care about all this? Well, when we’re simplifying a square root, we’re really asking ourselves: “What pairs of numbers under this root can I take out?” You know how when you have a pair of shoes, you only need to wear one to grab the other? Kind of like that!

By identifying pairs, we can simplify √108 as follows:

[ \sqrt{108} = \sqrt{(2^2) \times (3^3)} ] We can regroup this expression a little by recognizing pairs of factors to pull out of the root: [ \sqrt{(2^2) \times (3^2) \times 3} = \sqrt{4} \times \sqrt{9} \times \sqrt{3} ] From there, it’s just a matter of simplifying what's outside and what's left inside the square root:

• √4 equals 2.
• √9 equals 3.

Now multiplying these numbers together gives us: [ 2 \times 3 \times \sqrt{3} = 6\sqrt{3}. ]

Voilà! There you have it: the simplified form of √108 is 6√3. You know what? Once you’ve mastered this approach, it can almost feel like having a superpower. And let's be honest, who wouldn’t want that?

Now let’s pause for a second. If this feels overwhelming, don't fret! You’re not the only one. Many students feel like math is a mountain they’re not quite ready to summit. But here’s the thing: practice makes perfect. Feel free to take a breather and revisit it later. Before you know it, that kernel of anxiety will turn into a blossoming confidence.

As you continue your study for the Kaplan Nursing Entrance Exam, remember that simplifying roots, understanding algebra, and grasping concepts like these will serve you well—not just on tests, but in your future endeavors in nursing. Let these numbers become your allies rather than foes. And who knows? One day, you might be explaining this very technique to someone else who’s struggling, lighting that same spark of understanding you’ve just uncovered.

So, take a moment to pat yourself on the back! Learning something new is worth celebrating. And while problems like √108 may come and go, your problem-solving skills? They’re here to stay! Keep practicing, and you’ll feel right at home with math in no time.
