XXXXXXXXX+177=9

Question

Figure out X

Answer 1

Whenever solving for X, the goal is to get it by itself, and remove all other numbers from that side of the equation. It is also best to begin with a simplified version of the equaiton. Therefore, we should begin by simplifying XXXXXXXXX to read X⁹, which is the same thing since it is X times itself 9 times. Now the equation reads X⁹ + 177 = 9. Next, we need to subtract 177 from both sides, so that the equation becomes X⁹ = -168. Finally, to solve for X, we can place the reciprical of 9 as the exponent to -168, so it becomes X = -168^(1/9) and X = 1.767 when rounded.

Answer 2

x⁹+177 = 9

x = (-168)^(1/9) ≈ -1.767
