Siapa yang tau,tolong di bantu yah,, thanks before,, biarpun hanya 1 nomor saja yang bisa di jawab nggak apa-apa,atau bisa jawab semua maka lebih bagus ,,

(9^m. 3^5. 27^3) /(3. 81^4) = (27)
(3^(2m) .3^5 . (3^3)^3 ) / ( 3. (3^4)^4)  = 3^3
(3^(2m+5+9)) / (3^(17) = 3^3
2m+5+9 - 17 = 3
2m - 3 = 3
2m = 6
m = 6/2  =3

(2^(n+4) - 2.2^n ) /(2. 2^(n+3)) + 2^-3=
(2^(n+4) - 2^(n+1) )/ (2^(n+3+1)  + 2^-3=
(2^n ( 2^4 - 2^1) / 2^n. (2^4)  + 2^-3=
(2^4 - 2^1) / (2^4) + 2^-3 =
(16 -2)/(16) + 1/8 =
14/16 + 2/16 =
16/16 = 1

(a/b)^(x-1) = (b/a)^(x-3)
(b/a)^-(x-1) = (b/a)^(x-3)
-(x-1) = x - 3
-x + 1 = x - 3
-x - x = -3 -1
-2x = - 4
x = -4/-2
x = 2
