Слайды и текст этой презентации
Слайд 1Arkalyk state pedagogical Institute named after
Y. Altynsarin
Theme:
Power
Prepared by:
Shoibasov A. M-31.
Слайд 2" People unfamiliar with algebra can not imagine the wonderful
things that can be achieved with the help of ...
called science."G.W Leibniz
Слайд 3Determination of a natural indicator
Powers of a with natural exponent
n is the product of n factors, each of which
is equal to a.
Слайд 5Determination of the zero indicator
The degree of a, not equal
to zero , with zero is equal to one
Слайд 6Multiplying powers with the same bases
For any number a and
any positive integers m and n
Multiplying powers with the same
bases of the base is left unchanged , and the figures add up
Слайд 7The division of powers with the same bases
For any
arbitrary natural
number
and m and n, such that m> n
When dividing powers
with the same base bases are left unchanged , and the dividend is subtracted from the index index divider
Слайд 8Exponentiation works
For any numbers a and b and any positive
integer n
With the construction of the power works erected in
the degree of each factor and multiply the results
Слайд 9Exponentiation degree
For any number and a random natural numbers m
and n
With the construction of the degree of the power
base is left unchanged , and the figures are multiplied
Слайд 10Exponentiation fraction
For any numbers a and b >0 and any
positive integer n
With the construction of the power fraction erected
in the degree of the numerator and denominator of the fraction
Слайд 11History of the number of degree
In his famous book "
Arithmetic " Diophantus of Alexandria described the first natural degree
Слайд 12Rene Descartes in his
"geometry" ( 1637 ) ,
we
find the current
designation of degrees
а2,а3,...
Слайд 13" Silences " Game
1. Follow these steps:
х11∙х∙х2 ;
х14 : х5 ; (а4)3
; (-За)2.2. Compare the expression to zero :
( - 5)7; (-6)18; (- 4)11. (-4)8 (- 5)18∙ (- 5)6; -(- 4)8.
3. Calculate the value of the expression :
-1∙ 32; (-1 ∙ 3)2 1∙(-3)2; - (2 ∙ 3)2; 12 ∙ (-3)2
Слайд 17Comparing expressions
Compare without performing calculations. Find the correct inequalities. From
their respective letters make up the name of the architect
, the project is the building of the Bolshoi Theater in Moscow was built in 1825 :
Слайд 18What number illustrates a circle?
Find out how many shows a
circle, if the shaded portion shows a specified number .
A record in the form of adegree .
