• Exponents are used to express large numbers in shorter form to

make them easy to read, understand, compare and operate upon.

• a × a × a × a = a4 (read as ‘a’ raised to the exponent 4 or the fourth

power of a), where ‘a’ is the base and 4 is the exponent and a4 is

called the exponential form. a × a × a × a is called the expanded

form.

• For any non-zero integers ‘a’ and ‘b’ and WHOLE numbers m and n,

(i) am × an = am+n

(ii) am ÷ an = am–n , m>n

(iii) (am)

n = amn

(iv) am × BM = (AB)

(v) am ÷ bm =

(vi) a0 = 1

(vii) (–1)EVEN number = 1

(viii) (–1)odd number = –1

• Any number can be expressed as a decimal number between 1.0

and 10.0 (including 1.0) multiplied by a power of 10. Such form of a

number is called its standard form or scientific notation.
