√3^(2x + 1) = 9^(x - 2)
3^(2x + 1)/2 = 3^2(x - 2)
(2x + 1)/2 = 2(2x - 2)
Kdua ruas kalikan 2
2x + 1 = 8x - 8
8x - 2x = 8 + 1
6x = 9
x = 9/6
x = 3/2 ✔

7'log 2 = a
2'log 3 = b

6'log 98
= 2'log 98 / 2'log 6
= 2'log (2 × 7²) / 2'log (2 × 3)
= (2'log 2 + 2 . 2'log 7) / (2'log 2 + 2'log 3)
= (1 + 2/a) / (1 + b)
= (a + 2) / (a + ab)
