Penyelesaian :
[tex] \sf {9}^{4x - 60} = 6.561[/tex]
[tex] \sf {9}^{4x - 60} = {9}^{4} [/tex]
[tex] \sf { \cancel9}^{4x - 60} = { \cancel9}^{4} [/tex]
[tex] \sf4x - 60 = 4[/tex]
[tex] \sf4x = 4 + 60[/tex]
[tex] \sf4x = 64[/tex]
[tex] \sf{}x = \frac{64}{4} [/tex]
[tex] \sf{}x = 16[/tex]
_________
4! + 2!
(4×3×2×1) + (2×1)
(12×2) + 2
24 + 2
= 26
