Satu lagiii , tolong dijawab yaa.. (1/25)^3x+1 = ³√5^x+2

(1/25)^3x + 1 = ³√5^x + 2
(5^-2)^3x + 1 = (5)^x+2/3
5^-6x-2 = (5)^x+2/3

-6x-2 = x+2/3
-18x-6 = x + 2
-18x - x = 2 + 6
-19x = 8
x = -8/19

Bab Eksponensial
Kelas X SMA
Matematika Minat
Kurikulum 2013

Persamaan Eksponensial

5 ^-2 (3x + 1) = 5 ^ x + 2
                         ------------
                               3

-6x - 2 = x + 2       (Kalikan kedua ruas dengan 3)
              -------
                 3

-18x - 6 = x + 2
-18x - x = 2 + 6
     -19x = 8
          x = 8/-19
 

Semoga Membantu!!!
