tolong kerjakan yang no 2 dan 3

2. a. 2^4 × 8 × 2^2 = 16 × 8 × 4 = 512
b. 25 + (15^2 × 2^3) = 25 + (225 × 8) = 25 + 1800 = 1825
c. (2/3)^3 × 3^2 × 12 = 8/27 × 9 × 12 = 8/3 × 12 = 8 × 4 = 32

3. a. 2 akar 128 = 2 akar 2×2×2×2×2×2×2 = 2 × 2×2×2 akar 2 = 16 akar 2
b. 3 akar 175 = 3 akar 5×5×7 = 3 × 5 akar 7 = 15 akar 7
c. 2 akar 147 = 2 akar 7×7×3 = 2 × 7 akar 3 = 14 akar 3

maaf kalo ada yg salah
