Tentukan himpunan penyelesaian dri
a.8 pangkat 4x-16 = 1
b.akar 6 pangkat 4x-2 = 216pankat2x-1
c(Xpangkat 2 + 4) pangkat x2+6x+9 = (-5x-2) pangkat x2+6x+9
a.8 pangkat 4x-16 = 1
b.akar 6 pangkat 4x-2 = 216pankat2x-1
c(Xpangkat 2 + 4) pangkat x2+6x+9 = (-5x-2) pangkat x2+6x+9
8^4x-16 = 8^0
4x-16 = 0
4x = 0+16
4x = 16
x = 16/4
x = 4
b) √(6^4x-2) = 216^2x-1
(6^4x-2)^1/2 = (6^3)^2x-1
(6)^2x-1 = (6)^6x-3
2x-1 = 6x-3
2x-6x = -3+1
-4x = -2
x = -2/-4
x = 1/2
c) blm kjawab
