Pasadya (4 ^ (x + 2) -2 ^ (2x + 1)) / (8 ^ x (4 ^ (1-x)) at ipahayag ito sa anyo ab ^ (x-2), kung saan a at b ay integer?
(2 ^ 2) ^ (x + 2) -2 ^ (2x + 1)) / ((2 ^ 3) (x ^ a) ^ b = x ^ (ab). (2 ^ (2x + 4) -2 ^ (2x + 1) (2 ^ (2xx4)) / (2 ^ (3x) (2 ^ (2-2x))) Pasimplehin ang denamineytor gamit ang panuntunan na x ^ a (x ^ b) 2 ^ (2x + 1)) / (2 ^ (x + 2)) / 2 (2x + 1) 2 ^ (x + 2) -2 ^ (x-1) Factor out a 2 ^ (x 2) (x-2) (2 ^ 4-2) I-simplify at isulat sa form na ab ^ (x-2) 14 (2 ^ (x-2))
