Question

What is the solution for: 10n^2+n^2+16

Answer 1

The solution is n= + 4i/√11

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 complex term 'i')

n= + 4i/√11
