( 517 X 517 X 517 + 483 X 483 X 483)/(517 X 517 – 517 X 483 + 483 X 483). Find the result of this
expression.
A. 1
B. 1000
C. 5436948
D. 23,45,683

• B.
  Cuz, a3+b3=(a+b)(a2-ab+b2)
  so [(a+b)(a2-ab+b2)] / (a2-ab+b2)= a+b=517+483=1000.

  explaination-
  a+b=(a^3+b^3)/(a^2-ab+b^2)
• 9 years agoHelpfull: Yes(0) No(0)
• a+b = 517+483 =1000
• 9 years agoHelpfull: Yes(0) No(0)
• b.1000
  as it is of the form (a^3+b^3)/(a^2-a*b+b^3)
• 9 years agoHelpfull: Yes(0) No(0)
• a=517,b=483
  a+b=517+483=1000
• 9 years agoHelpfull: Yes(0) No(0)
• 517+483=1000
• 9 years agoHelpfull: Yes(0) No(0)
• B.1000
  as a^3+b^3=(a+b)(a^2-ab+b^2)
• 9 years agoHelpfull: Yes(0) No(0)
• 1ooo this is very simple a^3+b^3=(a+b)(a^2-ab+b^2)
• 9 years agoHelpfull: Yes(0) No(0)
• a=517,b=483
  then it means
  (a^3+b^3)/(a^2-ab+b^2)=(a+b)(a^2-ab+b^2)/(a^2-ab+b^2)=a+b
  then ans is 517+483=1000
• 9 years agoHelpfull: Yes(0) No(0)
• B.1000
  The result of the question according to BODMAS rule
• 9 years agoHelpfull: Yes(0) No(0)
• ANSWER B
  APPLYING THE ( a^3+b^3) formula
• 9 years agoHelpfull: Yes(0) No(0)
• 10000
  a+b=1000
• 9 years agoHelpfull: Yes(0) No(1)
• B. 1000
  since it is in the form (a^3+b^3)/(a^2-ab+b^2) = a+b
  so 517+483 = 1000
• 9 years agoHelpfull: Yes(0) No(0)
• 1000
  formula a^3+b^=(a+b)(a^2-ab+b^2) then
  517+483=1000
• 9 years agoHelpfull: Yes(0) No(0)
• its in terms of formula in the numerator and as well as in denominator
  numerator= (517x517x517+483x483x483)
  (517^3+483^3) = (a^3+b^3) = (a+b) (a^2-ab+b^2)
  denominator = (517x517-517x483+483x483) = (a^2-ab+b^2)
  therefore , (a^2-ab+b^2) will get cancelled & remaining is (a+b)
  which equals 517+483 = 1000.
  
• 9 years agoHelpfull: Yes(0) No(0)
• (a^3+B^3)/(A^2-ab+b^2) = (a+b). so, 517+483 = 1000
  
• 9 years agoHelpfull: Yes(0) No(1)
• a^3+b^3=(a+b)(a^2-ab+b^2)
  so answer should be (a+b)=517+483=1000
• 9 years agoHelpfull: Yes(0) No(0)
• It just look like ((a*a*a)+(b*b*b))/((a*a)-(a*b)+(b*b))-------> a3+b3/(a2-ab+b2)
  we know that a3+b3=(a+b)(a2-ab+b2)
  so, a+b is our result
  i.e; = 517+483-------->1000
• 8 years agoHelpfull: Yes(0) No(0)
• a^3+b^3=( a+b)(a^2-ab+b^2)
  Use above formula
• 8 years agoHelpfull: Yes(0) No(0)
• =>(a^3+b^3)/(a^2-ab+b^2)
  =>(a+b)(a^2-ab+b^2) / (a^2-ab+b^2)
  =>a+b
  =>a=517 and b=483 then a+b=1000
