"Division of Integers" PPT courseware on operations of integers

Review the rule for dividing powers with the same base:

When powers with the same base are divided, the base remains unchanged and the exponents are subtracted.

That is, am÷an=am-n (a≠0, m, n are all positive integers, and m>n)

The moon is the closest celestial body to the earth, and its average distance from the earth is about 3.8×108 meters. If the spacecraft flies at a speed of 1.12×104 meters/second, how long does it take to reach the moon?

(3.8×108)÷(1.12×104)

Rule for dividing a monomial by a monomial

For monomial division, divide the coefficients and powers with the same base as the factors of the quotient. For letters contained only in the dividend, they are used together with their exponents as a factor of the quotient.

Fill it out

(1) (625+125+50)÷25=( )÷( )+( )÷( )+( )÷( )=( )+( )+( )=( )

(2) (4a+6)÷2=( )÷2+( )÷2=( )

(3) (2a2-4a)÷(-2a)=( )÷(-2a)+( )÷(-2a) =( )

Discuss

Have you found the rule for dividing polynomials by monomials?

To divide a polynomial by a monomial, first divide each term of the polynomial by the monomial, and then add the resulting quotients.

Try your hand

(1) (10ab3)÷(5b2)

(2) 3a3÷(6a6)·(-2a4)

(3)(4c3d2-6c2d3)÷(-3c2d)

Practice filling in the blanks

①( )·3ab2=-9ab5

② [3a2-( )]÷(-a)=-3a＋2b

③( )·(-2y)=4x2y-6xy2

Distinguish between right and wrong

(1) (2x-4y+3)÷2=x-2y+3

(2) (8x2y-4xy2)÷(-4xy)=-2x-2y

(3) (3x2y-3xy2+x)÷x＝3xy-3y2

feel the experience

(1) (5x3-2x2+6x) ÷3x

(2) (2x2y3) (-7x2y2) ÷ (14x4y3)

(3)-x.(3xy-6x2y2) ÷(3x2)
