Comparison of square roots: Which is smaller, √81 or √1?

Introduction / Context: Basic comparison of square roots of perfect squares.

Given Data / Assumptions: Compare √81 and √1.

Concept / Approach: Compute both values directly.

Step-by-Step Solution: √81 = 9.√1 = 1.Thus the smaller value is √1.

Verification / Alternative check: None needed beyond direct evaluation.

Why Other Options Are Wrong: √81 is larger; they are not equal.

Common Pitfalls: None significant here.

Final Answer: √1
