$x^4-16+16=0+16$

Learn how to solve equations problems step by step online. Solve the equation x^4-16=0. We need to isolate the dependent variable x, we can do that by simultaneously subtracting -16 from both sides of the equation. Canceling terms on both sides. Removing the variable's exponent. Cancel exponents 4 and \frac{1}{4}.

$x=2,\:x=-2$
