Please Simplify:

Root 18-Root 50+4 Root 2 = ?

√18 - √50 + 4√2

= 3√2 - 5√2 + 4√2
= 2√2

Thanks just wanted to be sure!

To simplify the given expression, let's start by simplifying each individual square root term.

Step 1: Simplify √18:
√18 can be written as √9 * √2, since 9 is a perfect square. Thus, we have:
√18 = √9 * √2 = 3√2

Step 2: Simplify √50:
√50 can be written as √25 * √2, since 25 is a perfect square. Thus, we have:
√50 = √25 * √2 = 5√2

Step 3: Substitute the simplified square root terms back into the original expression:
3√2 - 5√2 + 4√2

Step 4: Combine the like terms:
(3 - 5 + 4)√2 = 2√2

So, the simplified form of √18 - √50 + 4√2 is 2√2.
