Exponent rules

 

What is an exponent

The base a raised to the power of n is equal to the multiplication of a, n times:

a n = × a × … × a

                    n times

a is the base and n is the exponent.

Examples

31 = 3

32 = 3 × 3 = 9

33 = 3 × 3 × 3 = 27

34 = 3 × 3 × 3 × 3 = 81

35 = 3 × 3 × 3 × 3 × 3 = 243

Exponents rules and properties

Product rules a n ? a m = a n+m 23 ? 24 = 23+4 = 128
a n ? b n = (? b) n 32 ? 42 = (3?4)2 = 144
Quotient rules a n / a m = a nm 25 / 23 = 25-3 = 4
a n / b n = (/ b) n 43 / 23 = (4/2)3 = 8
Power rules (bn)m = bn?m (23)2 = 23?2 = 64
bnm = b(nm) 232 = 2(32)= 512
m?(bn) = b n/m 2?(26) = 26/2 = 8
b1/n = n?b 81/3 = 3?8 = 2
Negative exponents b-n = 1 / bn 2-3 = 1/23 = 0.125
Zero rules b0 = 1 50 = 1
0n = 0 , for n>0 05 = 0
One rules b1 = b 51 = 5
1n = 1 15 = 1
Minus one rule (-1)5 = -1
Derivative rule (xn)‘ n?x n-1 (x3)‘ = 3?x3-1
Integral rule ? xndx = xn+1/(n+1)+C ? x2dx = x2+1/(2+1)+C
