Description

"Integer Exponential Powers" Fraction PPT teaching courseware

Part One: Learning Objectives

1. Understand and master the operational properties of negative integer exponential powers. (Key points)

2. Understand the properties of integer exponential powers and apply them to solve practical problems. (difficulty)

Review old knowledge

What are the algorithms for raising positive integer exponential powers?

(1) am·an=am+n (m and n are both positive integers);

(2) (am)n=amn (m, n are both positive integers);

(3) (ab)n=anbn (n is a positive integer);

(4) am ÷an=am-n (a ≠0, m,n are positive integers, m>n);

Integer exponent power PPT, part 2: exploring new knowledge

Calculation: a3 ÷a5=? (a ≠0) How many solutions do you have?

Calculation: a0 ÷an=? (a ≠0)

Generally, we stipulate that when n is a positive integer,

That is to say, a-n (a≠0) is the reciprocal of an.

Integer Exponential Power PPT, Part 3: Classroom Exercises

Example 1(1)-22= _____, (2)(-2)2= _____,

(3) (-2) 0=_____, (4) 20= ________,

(5) 2-3=________, (6) (-2)-3= _____,

Integer exponent power PPT, part 4 content: Class summary

(1)am·an=am+n (m and n are integers);

(2)(am)n=amn (m, n are integers);

(3)(ab)n=anbn (n is an integer).

(4)am ÷an=am-n (a ≠0, m,n are integers)

Note: If there are no special requirements, if the result contains a negative integer exponent, it should generally be converted into a fractional form.
