tolong bantu yh, makasiee!!
Jawaban:
ini jawaban yang nomor 3 ya kak
pembahasan :
13^(x² - 5x - 14) = 1
13^(x² - 5x - 14) = 13^0
x² - 5x - 14 = 0
(x - 7)(x + 2) = 0
x - 7 = 0, x + 2 = 0
x = 7, x = -2
HP : {-2, 7}
soal 2:
(¼)^(x + 2) = 16^(¼)
(4⁻²)^(x+2) = (4²)^(¼)
4^(-2x-4) = 4^(2/4)
-2x-4 = 2/4
-2x- 4 = ½
-2x = 4-½
-2x = 3,5
x = -1,75
soal3:
2^(3x-8) = 16
2^(3x-8) = 2⁴
3x - 8 = 4
3x = 12
x = 4
