|5||Divisibility by 9||The sum of digits should be divisible by 9|
|6||Divisibility by 11||The 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
(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 the equality.
(a + b)2 = a2 + 2ab + b2
(a – b)2 = a2 – 2ab + b2
(a + b) (a – b) = a2– b2
(x + a) (x + b) = x2 + (a + b) x + ab
