a0 1 Exponent is 0
a1 a  Exponent is 1
a2 a x a Exponent is 2
a3 a x a x a Exponent is 3
a4 a x a x a x a Exponent is 4
a5 a x a x a x a x a Exponent is 5
   ('a' is the BASE)  
     
100 1 Exponent is 0
101 10  Exponent is 1
102 100 Exponent is 2
103 1000 Exponent is 3
104 10000 Exponent is 4
105 100000 Exponent is 5
   ('10' is the BASE)  

 

Multiplication of numbers (of the same base) results in the addition of the exponents

Eg. 102 x 103 = 105 Division of numbers (of the same base) results in the subtraction of the exponents Eg. 102 / 103 = 10-1 The reciprocal (1/the number) can be found by reversing the sign of the exponent Eg. 1/104 = 10-4 A power of the number can be found by multiplying the exponent by that power Eg. (104 )3 = 1012 A root of the number can be found by dividing the exponent by that root Eg. The square root of 1042 = 1021
Eg. The cube root of 1042 = 1014
