2 pangkat X +5 +2 pangkat 5-x =64 x=.........

2^(x + 5) + 2^(5-x) = 64
2^x. 2^5 + 2^5. 2^-x = 64

misal →
2^x = t

soal menjadi
t.32 + 32.1/t = 64
32t + 32/t = 64 ----- dikali t
32t² + 32 = 64t
32t² - 64t + 32 = 0
t² - 2t + 1 = 0
(t - 1)(t - 1) = 0
t = 1

2^x = t
2^x = 1
2^x = 2⁰
x = 0

semoga berguna
