Term 1 has a square root, so we evaluate and simplify:
Simplify √64.
If you use a guess and check method, you see that 72 = 49 and 92 = 81. Since 49 < 64 < 81 the next logical step would be checking 82.
82 = 8 x 8 82 = 64 <--- We match our original number!!! Therefore, √64 = ±8
The principal root is the positive square root, so we have a principal root of 8
Group constants
8 = 8
Final Answer:
8
