  1. x=27
  1. First, since you are multiplying by 99 you have to do the opposite and divide by 99 on both sides to get x^2+9^3= 1458
  1. Next, you get rid of the exponent on the 9^3 by multiplying 9 * 9 * 9 to get 729 and subtract from both sides to get x^2 = 729
  1. Finally, you get rid of the exponent on the x by taking the square root of both sides to get x = 27
