Greetings!

When multiplying two roots together that are the same inside the root, you can simply multiply the two roots together:


[tex]\sqrt{2}[/tex] x [tex]\sqrt{2}[/tex] = 2

Then you can multiply this product by the number infront of the first root:


2 x 4 = 8

So the answer would be 8!

Hope this helps!
