Mar 3, 2021 #2 tradBohus said: Why is sqrt(2)^3 = 2*sqrt(2)? Add a comment. Using earlier results to simplify proofs of later results happens all the time in maths (though usually on a somewhat bigger scale, but still). So the concept of simplifying square roots is like the concept of simplifying other things like exponents, parentheses, etc. [1] For example, 4 and −4 are square roots of 16 because . Consequently, the domain of f is Algebra. Step 2: Make pairs of identical factors. Tap for more steps 4√2 4 2 The result can be shown in multiple forms. Pull terms out from under the radical. For example, √ 25 = 5, since 25 = 5 ⋅ 5, or 52 (5 squared).e. And this is true since $\mathbb{Q}(\sqrt{2})$ and $\mathbb{Q}(\sqrt{5})$ each have a unique (up to rational multiple) element of trace $0$, and $\sqrt{2}, \sqrt{5}$ can't be rational multiples of each other since $2/5$ isn't a square.
