S.noDivisibilityHow it works
1Divisibility by 10Numbers ending with 0 are divisible by 10
2Divisibility by 5Numbers ending with 0 and 5 are divisible by 5
 
3Divisibility by 2Numbers ending with 0,2,4,6 and 8 are divisible by 2
 
4Divisibility by 3The sum of digits should be divisible by 3
5 Divisibility by 9The sum of digits should be divisible by 9
6Divisibility by 11The difference between the sum of digits at its odd places and that of digits at the even places should be divisible by 11

Laws of Exponents

Here are the laws of exponents when a and b are non-zero integers and m, n are any integers.

a-m = 1/am

am / an = am-n

(am )n     = amn

am x bm  = (ab)m

am / bm   = (a/b)m

a0 =1

(a/b)-m =(b/a)m

(1)n = 1 for infinitely many n.



(-1)p =1  for any even integer p

What is an Identity

An identity is an equality, which is true for all values of the variables in equality.

(a + b)2 = a2 + 2ab + b2

(a b)2 = a2 – 2ab + b2

(a + b) (a b) = a2b2

(x + a) (x + b) = x2 + (a + b) x + ab
