5.1 Indices and Laws of Indices (Part 1)
(A) Zero Indices
The zero index of any number is equal to one.

 a 0 = 1, where a ≠ 0

Example 1:
Find the value of the followings:
(a) 2500
(b) 0.5130

Solution:
(a) 2500 = 1
(b) 0.5130 = 1

(B) Negative Integral Indices

Example 2:
Find the value of the followings:
(a) 102 -1
(b)  –6 -3

Solution:
