[9^{(x+4)/2}]•[9^(-4/2)] 9^(x+4)/2-4/2=9^1 (2x+8-8)/4=1 2x=4 x=2 you can check it buy putting in equation

Jaime :

Good vid

Nikaidō Hiro :

no

ybrik :

can't you just shortcut it by making the denominator 9², making the numerator 9^(x+4)/2. (x+4)/2 = 3 (because it has to be 1 more than the denominator to cancel out and be left with 9/1) x+4 = 6 x = 6-4 x = 2
