4%5E%28n%2B3%29%2A16%5En=8%5E%283n%29
=4%5En%2A4%5E3%2A%282%2A8%29%5En=8%5E%283n%29
=4%5En%2A4%5E3%2A2%5En%2A8%5En=8%5E%283n%29
=4%5En%2A2%5En%2A4%5E3%2A8%5En=8%5E%283n%29
=%284%2A2%29%5En%2A8%5E2%2A8%5En=8%5E%283n%29
=8%5En%2A8%5E2%2A8%5En=8%5E%283n%29
=8%5E%28n%2B2%2Bn%29=8%5E%283n%29
=8%5E%282n%2B2%29=8%5E%283n%29
_______________
SO,
2n+2=3n
2=3n-2n
2=n
_______________
Thus, solution for this equation is n=2
