A) 1
B) 2
C) 789
D) 1103
Correct Answer: B
Solution :
Let 946 be a and 157 be b: \[\frac{{{(a+b)}^{2}}+{{(a-b)}^{2}}}{({{a}^{2}}+{{b}^{2}})}\] \[=\frac{{{a}^{2}}+{{b}^{2}}+2ab+{{a}^{2}}+{{b}^{2}}-2ab}{({{a}^{2}}+{{b}^{2}})}\] \[=\frac{2\,\,({{a}^{2}}+{{b}^{2}})}{({{a}^{2}}+{{b}^{2}})}=2\]You need to login to perform this action.
