# SOLUTION: 8x exp. -4 times 2x exp. -3 times x exp. 7 = 16 ? 8 times 2 = 16 -4 + -3 = -7 exponent so 16x exp. -7 then 16x exp. -7 times x exp. 7 = 16x exp. 0. (cause -7 +7=0) so

 Question 360538: 8x exp. -4 times 2x exp. -3 times x exp. 7 = 16 ? 8 times 2 = 16 -4 + -3 = -7 exponent so 16x exp. -7 then 16x exp. -7 times x exp. 7 = 16x exp. 0. (cause -7 +7=0) so 16x exp. 0 = 16 (cause x to the 0 = 1) Is that right? Answer by stanbon(57236)   (Show Source): You can put this solution on YOUR website!8x exp. -4 times 2x exp. -3 times x exp. 7 = 16 ? ----------------- 8x^-4 * 2x^-3 * x^7 = 16 ----- 16x^0 = 16 16 = 16 --- The equation is true for all Real Number values of x except x = 0. ================ Cheers, Stan H.
