Answer 1

The equation x² + 81 = (x + 10)² is equivalent to $\sqrt{x^2 + 81} = x + 10$

How to determine the equivalent equation?

The equation is given as:

$\sqrt{x^2 + 81} = x + 10$

Square both sides

x² + 81 = (x + 10)²

Although it can be further simplified, the above equation is equivalent to $\sqrt{x^2 + 81} = x + 10$
