Respuesta :

yes it is equivalent to the original question.
No. That would be False.

Squaring different numbers increases it exponentially, not proportionally.

For example:

1 + 2 = 3

[tex]1 ^{2} + 2^{2} \neq 3^{2} [/tex]

[tex]1 ^{2} +2 ^{2} =5[/tex]
[tex] 3^{2} =9[/tex]

I hope this helped!! :D
