$x=-6,6$; Warrick forgot to write the negative answer.

Work Step by Step

Isolate the variable factor on one side, and then take the $n$th root of both sides to solve for the variable. If the root is even, there will be a positive and negative answer. If the root is odd and the other side is negative, there is only a negative answer. $x^4=1296$ $x=\sqrt[4] {1296}$ $x=-6,6$ Warrick forgot to write the negative answer.
