The answer is C.

If we square both sides of the equation,  we can rid of the exponent on the right side and add a square root to  x + 4

The equation can be written as x+4=x^2 is \sqrt{x+4} =x, where x>0.

[tex]\sqrt{x+4} =x[/tex]

If we square both sides of the equation

We can rid of the exponent on the right side and add a square root to

x + 4.

[tex]\sqrt{x+4}=x[/tex]

Squaring on both sides we have,

What is the square root?

The square root of a number is that factor of a number that when multiplied by itself gives the original number.

[tex](\sqrt{x+4}})^2=x^2[/tex]

x+4=x^2

Therefore, The equation can be rewritten as x + 4 = x^2.
