KETENTUAN

a^P = a . a . a . a . . . . . . . . . . . . . . . . . sampai p faktor

(a dinamakan bilangan pokok, p dinamakan pangkat atau eksponen)

 

SIFAT-SIFAT

1. ap . aq = ap + q	5. a0 = 1
2. ap . aq = ap - q	6.  a - p = 1/ap
3. (ap)q = apq	7. am/n = nÖ(am)
4. (a.b)p = ap . bp

 

contoh:

1. 3^pq+q . 3^2p)/(3^pq+p . 3^2q) = (3^pq+q+2p)/(3^pq+p+2q) = 3^p-q
   
   
2. (0,0001)^-1 Ö0,04 = (10^-4)^-1(0,2) = (10⁴)(0,2) = 2000
   
   
3. (0,5)² + 1/⁵Ö32 + ³Ö0,125 = 0,25 + 1/2 + 0,5 = 1,25
   [ket : 32 = 2⁵ ; 0,125 = (0,5)³ ]
   
   
4. Apabila p = 16 dan q = 27, maka
   
   2p^-1/2 - 3p⁰ + q^4/3 = 2(2⁴)^-1/2 - 3(2⁴)⁰ + (3³)^4/3
                               = 2(2^-2) - 3(1) + 3⁴ = 2^-1 -3(1) + 81
                               = 1/2 - 3 + 81 = 78 1/2
