In relation to this, what's reputation and how do I get it? Instead, you can save this post to reference later. Why can I square both sides? we can square both side like this: $ x^2= 2$ But I don't understand why that it's okay to square both sides.

What I learned is that adding, subtracting, multiplying, or dividing both sides by the same thing is okay. For example: $ x = 1 $ $ x-1 = 1-1 $ $ x-1 = 0 $ $ x \times 2 = 1 \times 2 $ $ 2x = 2 $ like this. It's important to note that, but how come squaring both ...

algebra precalculus - How to square both the sides of an equation .... In relation to this, 2 You can square it like that, and the equality will still hold - remember these expressions are equal, so squaring them mean they are still equal. This can, however, produce spurious solutions - if you do this you should check that the values you get do indeed solve the given equation. Inequality proof, why isn't squaring by both sides permissible?.

7 Short answer: We can't simply square both sides because that's exactly what we're trying to prove: $$0 < a < b \implies a^2 < b^2$$ More somewhat related details: I think it may be a common misconception that simply squaring both sides of an inequality is ok because we can do it indiscriminately with equalities. It's important to note that, an example of a square-zero ideal - Mathematics Stack Exchange. Isn't square root a bit like Log()? I took a look at square root. Squaring the number means x^2.

And if I understood the square root correctly it does a bit inverse of squaring a number and gets back the x. I had a friend tell me a while ago that Log() is also opposite of exponent, wouldn't that mean that square root is like a variant of Log () that only inverse a squared number? Why sqrt(4) isn't equall to-2? If you want the negative square root, that would be $-\sqrt {4} = -2$.

Both $-2$ and $2$ are square roots of $4$, but the notation $\sqrt {4}$ corresponds to only the positive square root. Building on this, how do you find the closest square number to another number without .... Say we try to find the closest square number to 26.

we already know the closest square number is $25$. In relation to this, however, how do I calculate out 25? Because, if I try to prime factorize it like so: $\\s...
