The solution is n= <u>+</u> 4i/√11
Step-by-step explanation:
step 1: 10n^2+n^2+16=0
step 2: 11n^2+16=0
step 3: 11n^2= -16
step 4: n^2= -16/11
step 5: taking square root on both sides,
             n= √(-16)/√11 (square root of a negative number is a <u>complex term</u> 'i')
             n= <u>+</u> 4i/√11
 
        
             
        
        
        
Answer:
I’m pretty sure the answer is A.
