Question

I have a question: Does square root(o(square)+3(square) = 0+3

Answer 1

yes

Answer 2

Faris, in the equation editor, type sqrt{} to do a square root, and ^{} to do powers.

Answer 3

no:\[\sqrt{a^2+b^2}\ne a+b\]\[\sqrt{0^2+3^2}=\sqrt{0+9}=\sqrt{9}=\pm3\]

Answer 4

e.g.:\[\sqrt{4^2+3^2}=\sqrt{16+9}=\sqrt{25}=\pm5\]\[\sqrt{4^2+3^2}\ne4+3\]

Answer 5
