Description

"Powers raised to powers and products raised to powers" Multiplication and division of integers PPT download

Part One: Learning Objectives

1. Correctly use the multiplication rules of powers to perform power-related operations and solve some practical problems.

2. Cultivate students’ good habits of analyzing and solving problems.

Powers raised to powers and products raised to power PPT, part two: activity exploration

Exploration Point 1: The Rule of Multiplication of Powers

(102)3=( )×( )×( )

=10( )+( )+( )

=10( ) ×( )

=10();

(23)6=( )×( ) ×( )×( ) ×( )×( )

=2( )+( )+( )+ ( )+( )+( )

=2( ) ×( )

=2( )

Imitate calculations and look for patterns

(6 3)2=( )×( )= 6( )

(108)3=_______=_______

Based on the above calculations and reasoning, what conclusion did you draw?

When raising powers, the base remains unchanged and the exponents are multiplied.

Analysis of typical cases

Example 1 Calculation

(1) (102) 3; (2) (b5) 5; (3) (an) 3;

(4)-(x2)m; (5)(y2)3·y; (6)2(a2)6-(a3)4

Exploration point 2: Inverse operation of powers

Observing the following equation, what conclusion can you draw?
