Answer:
a
Explanation:
1. Reduce the index of the radical and exponent with 2
√(a^2) = a
Basically square root is also can be represent as power of 1/2. Which is (a^2)^1/2. Then you can multiply both power. So you will get a^(2/2). solve it hence the solution is a^1 which is a. Hopefully this will help
