Full solution

Q. Simplify:\newline(81)2=(\sqrt{81})^2 = _____
  1. Apply inverse operations: We start with the expression (81)2(\sqrt{81})^2. The square root and the square operation are inverse operations, so they cancel each other out, leaving us with the number under the square root.
  2. Calculate the expression: Calculating (81)2(\sqrt{81})^2 gives us 8181, because 81\sqrt{81} is 99, and 99 squared is 8181.
