Step-by-step explanation:

Answer 2

Answer:

The answer is √2.

Step-by-step explanation:

The operation can be expressed like:

$\sqrt{5*10} - 4\sqrt{2}$

You have to multiply what's inside of the first root

$\sqrt{50} -4\sqrt{2}$

Then, you have to find the factors of 50 which are 5²×2.

$\sqrt{25*2} -4\sqrt{2}$

If there's a squared number inside a square root, you can take it out of the square root.

$\sqrt{5^{2} *2} -4\sqrt{2}$

And now, you can subtract the square roots as the have the same radical term (2), so 5-4 = 1

$5\sqrt{2} -4\sqrt{2}$

$1\sqrt{2}$ or $\sqrt{2}$
