\( 2(t-8)^{2}+2=100 \) \( t= \) Entry Tip: Do not use a decimal approximation for square roots. To enter a number like type \( 5 * \) sqrt(7). Preview your answer before submitting! Furthere Tip: Write your answers as a list, with your answers separated by (a) comma(s). example, if you get 4 and \( -\frac{2}{3} \) as your answers, then enter \( 4,-2 / 3 \) in the box.
