nilai x yang memenuhi 8^x+1=32^2x-5

Bab Eksponensial
Matematika SMP Kelas IX

^ = pangkat

8^(x + 1) = 32^(2x - 5)
(2^3)^(x + 1) = (2^5)^(2x - 5)
3 (x + 1) = 5 (2x - 5)
3x + 3 = 10x - 25
3x - 10x = -25 - 3
-7x = -28
x = -28/-7
x = 4

HP = { 4 }

8^(x + 1) = 32^(2x - 5)
2^3(x + 1) = 2^5(2x - 5)
3(x + 1) = 5(2x - 5)
3x - 10x = -3 - 25
-7x = -28
x = 4 ✔
