(2^1/2)^4x+6 = (2)^4
(2)^2x+3 = (2)^4
krn bilangan pokoknya sama, eksponen bs turun lgsg :
2x+3 = 4
2x = 4-3
2x = 1
x = 1/2
i) 9^x+3/2 = 1/81
(3²)^x+3/2 = (3)^-4
(3)^x+3 = (3)^-4
bilangan pokoknya sama,maka eksponen bs lgsg turun :
x+3 = -4
x = -4-3
x = -7
3 pangkat 3x-2 = 3 pangkat 4
3x-2+2 = 4+2
3x = 6 kedua ruas dikalikan 1/3
x = 2
