I am going to assume you meant to write 4w as \(\sqrt{4w}\) instead.
If so, then this question is pretty simple. A radical sign, √, indicates a square root of any given number located under it. Since 4w is under the radical we will be finding the square root of 4w. Since w is a variable and there is no square root we will have to just take the square root of 4 instead. So, our answer should look like this:
\(2 \sqrt{w}\)
This basically says "2 times the square root of w"
I hope this helped!! Have an amazing day :))
