 Introduction

 Recall

 Rules of Exponents

 Exercise
At the end of the lesson the students will be able to

- know the basic rules of exponents and radicals.

- apply the basic properties and rules of exponents

- enhance students' deductive reasoning by solving
the problem of exponents and radicals.

45 minutes / Student-centred
In general, if b is a real number and n is a positive integer,
then we may write-
b.b.b….b = bn
n factors

and call bn, the nth power of b.

exponent
bn = the nth power of b
base

In b.b.b = b3, b3 is called the exponential form, b.b.b is called
the factored form or exponded form.
Rule 1.

Rule of Multiplication


bm x bn = bm+n

Rule of Division

bm
= bm-n
bn
