1. ## Reducing/Simplifying square root

During my work with reducing/simplifying, have I faced a new problem. This time is about reducing/square root the square root.

√(a2 + b2 - 2ab)

My solution looks like this, but i'm not sure, if there is anything more to do, or if it's even correct.

a + b - 2ab0.5

Realize that $\sqrt{x^2}=|x|$ also $a^2+b^2-2ab=(a-b)^2$.

Put those together and what is the answer.

I know your answer is wrong because square root of 2 is a very long number and multiplying by 0.5 wont give you the same answer.

Thanks! Haven't thought of factorize before finding the square root.
