Question

$MF#%\dfrac{719 \times 719 + 347 \times 347 - 719 \times 347}{719 \times 719 \times 719 + 347 \times 347 \times 347} = ?$MF#%
Options:
A .  $MF#%\dfrac{1}{372}$MF#%
B .  $MF#%\dfrac{25}{133}$MF#%
C .  $MF#%\dfrac{1}{1066}$MF#%
D .  $MF#%\dfrac{5}{6}$MF#%
Answer: Option C

Answer : Option C

Explanation :

$MF#%\text{The given statement is in the form }\dfrac{a^2 + b^2 - ab}{a^3 + b^3}\text{ where a = 719 and b = 347}$MF#%

$MF#%\dfrac{a^2 + b^2 - ab}{a^3 + b^3} = \dfrac{(a^2 + b^2 - ab)}{(a + b)(a^2 - ab + b^2)} = \dfrac{1}{a + b} = \dfrac{1}{719 + 347} = \dfrac{1}{719 + 347} = \dfrac{1}{1066}$MF#%
