The calculation and factorization of grade one in junior high school calculation （-2003)×2÷1/2+(-1/3)^-2÷2^-3 2011^2-2010*2012 Factorization 4X^2-64 -X^2+2X^2-X Simplification (3X+2)(3X-2)-5X(X-1)-(2X-1)^2

(-2003)×2÷(1/2) + (-1/3)^(-2)÷2^(-3)= -2003×2×2 + [(-3)^2]×(2^3)= -8012 + 9×8= -79402011^2 - 2010×2012= 2011^2 - (2011-1)×(2011+1)= 2011^2 - (2011^2 -1)= 14X^2-64= 4(X^2 - 16)= 4(X^2 - 4^2)= ...

Calculation by factorization. 1 996-178; - 16. 2 2005003-2003 × 2002

⒈996²－16.
=(996+4)(996-4)
=1000×992
=992000
⒉2005003－2003×2002.
=2003×1001-2003×2002
=2003(1001-2002)
=-2005003

A problem related to factorization -- erasing the common factor: 2002 ^ 3 + 2002 ^ 2-2003 / 2002 ^ 3-2 times 2002 ^ 2-2000

2002 ^ 3 + 2002 ^ 2-2003: 2002 ^ 3-2 times 2002 ^ 2-2000
Let 2002 = a
(a^3-2a^2-a+2)/(a^3+a^2-a-1)
=(a+1)(a-1)(a-2)/(a+1)^2(a-1)
=(a-2)/(a+1)
=2000/2003

How many meters is three fourths of a kilometer

3 / 4 km = 0.75 km = 750 m

3.08 km=______ Rice

3.08 × 1000 = 3080, so 3.08 km = 3080 M

How many kilometers are eight and three fifths of a kilometer?

8 km 600 m

What's the ratio of 3.5 cm to 7 km

3.5cm: 7km
=3.5cm: 700000cm
=1：2000000

How many inches is 2 meters?

2 meters = 60 inches

How many decimeters is 2 meters?

20

What is 2000 a minus 2000

2000[a-1]
