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
