Jawaban nya gimana tuh

Jawab:

Penjelasan dengan langkah-langkah:

a]

4^V[9^(x - 5)] = 1/81

(9^(x - 5))^1/4 = 81^(-1)

9^(x - 5)/4 = (9^2)^('1)

9^(x - 5)/4 = 9^(-2)

(x - 5)/4 = -2

x - 5 = -2 × 4

x - 5 = -8

x = -8 + 5

x = -3

HP = {-3}

b]

(x - 3)^(2x - 1) = (x - 3)^(x + 1)

2x - 1 = x + 1

2x - x = 1 + 1

x = 2

HP = {2}
