[tex]nilai x dari {2}^{ \times 2 + 5 \times + 2} = \frac{1}{16} [/tex] di fotoin ya cara kerjanya kak

[tex] {2}^{ {x}^{2} + 5x + 2} = \frac{1}{16} \\ {2}^{ {x}^{2} + 5x + 2} = {2}^{- 4} \\hilangkan \: 2 \: karena \: basis \: sudah \: sama \\ {x}^{2} + 5x + 2 = - 4 \\ {x}^{2} + 5x + 2 + 4 = 0 \\ {x}^{2} + 5x + 6 = 0 \\ (x + 3)(x + 2) = 0 \\ x = - 3 \: atau \: x = - 2[/tex]
