A) \[13\]
B) \[\sqrt{13}\]
C) \[169\]
D) \[13\sqrt{13}\]
E) \[{{(169)}^{2}}\]
Correct Answer: A
Solution :
\[\frac{4230-1846}{16}={{?}^{2}}-20\] \[\Rightarrow \frac{2384}{16}={{?}^{2}}-20\] \[\Rightarrow \,149+20={{?}^{2}}\] \[\Rightarrow \,{{?}^{2}}=169={{13}^{2}}\] \[\therefore \,\,\,?=13\]You need to login to perform this action.
