learning target
1. Through the operational properties of multiplication of powers with the same base, you can derive the operational properties of division of powers with the same base.
2. Be able to use the operational properties of division of powers with the same base to perform calculations.
3. Able to use the arithmetic properties of exponential powers with the same base to perform calculations.
Review the past and learn the new
Exercise 1:
1. Calculation:
(1) (-2)3•(-2)2; (2) a5•a2;
(3) (-2)4·22; (4)-a2·a3;
(5)(-a)2•a3; (6)(a-b)•(a-b)2;
Question 2: What do the two powers in the following four questions have in common?
(1)105÷103;
(2) 27 ÷ 23;
(3) a9÷a4;
(4)(-a)10 ÷ (-a) 2.
Question 3: Please calculate the results of each of the above questions.
(1)105÷103 =102
(2)27 ÷ 23 =24
(3) a9÷ a4 =a5
(4)(-a)10 ÷(-a)2=(-a)8
communication and discovery
Divide powers with the same base, keep the base unchanged, and subtract the exponents
am÷an=am-n
(where a≠0, m,n are all positive integers, and m>n)
think:
(1) Discussion: Why is it noted that a≠0? m>n?
(2) Can you describe the rule of division of powers with the same base in written language?
Classroom meets standards
1. Calculate the following equations:
(1)x5÷x4÷x (2)y9÷y6÷y2
(3) a5÷a4.a2 (4) y8÷(y6÷y2)
(5) (a3)5÷(a2)3 (6)xn-1÷x·x3-n
(7)-(y5·y4)÷(y3·y4)
(8) (-x)8÷(-x)2-x4•x2.
2. It is known that am=2, an=3, find:
(1) The value of am-n; (2) The value of a2m-n.
extracurricular extension
1. Calculate:
(1) (a-b)7 ÷ (b-a)3 = -(a-b)4
(2) m19 ÷ m14 � m3 ÷ m =m7
(3) (b2 ) 3 �(-b 3)4 ÷(b 5)3 = b3
(4) 98 � 27 2 ÷ (-3) 18 =81
2. Given: 812x÷92x÷3x=729, find the value of x.
