Question

If x^2=4 then x=2 pleas help me ​

Answer 1

`x^2=4\Longrightarrow x=4^{2^(-1)}=4^{(1)/(2)}=√(4)=\boxed{2}`

So the first one is correct which implies that the third one is also correct.

But these are not the only ones.

`</p><p>2x=2\Longrightarrow x=(2)/(2)=\boxed{1}</p><p>`

The last one is also correct.

Hope this helps.
