How do I square $\\log_2(3)$ Does it become $2\\log_2(3)$ ?
- Why can I square both sides? - Mathematics Stack Exchange
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 But how come squaring both
- algebra precalculus - How to square both the sides of an equation . . .
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 isnt squaring by both sides permissible?
Short answer: We can't simply square both sides because that's exactly what we're trying to prove: $$0 < a < b \implies a^2 < b^2$$

Thus it now seems that a 3-dimensional structure whose base is a square with side $200$, whose top is a circle of diameter $100$, and whose height is $150$, cannot be constructed by bending and creasing a flat 2-dimensional shape

- Why get the sum of squares instead of the sum of absolute values?
Why do we square the differences? On one hand, it seems squaring them will allow us to get a positive number when the expected value is less than the actual value But why can't this just be accounted for by taking the sum of the absolute values? Like so: $$\sum_{i=1}^m |h(x_i)-y_i|$$
