1.n pangkat 2=9 2.3 pangkat n=27 3.2pangkat n+1=16 4.3pangkat 2n=81 5.2pangkat 3n-1=32

1. n^2 = 9
n^2 = 3^2
n = 3

2. 3^n = 27
3^n = 3^3
n = 3

3. 2^n+1 = 16
2^n+1 = 2^4
n+1 = 4
n = 4-1
n = 3

4. 3^2n = 81
3^2n = 3^4
2n = 4
n = 4/2
n = 2

5. 2^3n-1 = 32
2^3n-1 = 2^5
3n-1 = 5
3n = 5+1
3n = 6
n = 2

semoga membantu :)
