Asalamu'alaikum :)) Mau numpang nanya nih soal Matemtika :D

1. 2^12 x 2^(-15) = 2^(-3)

2. 3 (3^3)^1/3 + 4(2^5)^2/5
   = (3x3) + (4x2^2)
   = 9 + 16 = 25

3. 3^5x-1 = (3^3)^x+3
    3^5x-1 = 3^3x+9
     5x - 1 = 3x + 9
     5x - 3x = 9+1
         2x = 10
         x = 10/2
     x = 5
 

A. (2^3)^4 x (2^3)^-5 = 2^12 x 2^-15 = 2^12+-15 = 2^-3 atau 1/8 b. 3(27)^1/3 + 4(32)^2/5 = 3x3 + 4x2^ = 25 c. 3^5x-1 = 27^x+3, = 5x - 3x = 3 + 1, 2x = 4, x = 2
