Rounding $\sqrt{17}$ to Two Decimal Places

Round $\sqrt{17}$ to two decimal places by using a calculator and then applying the decimal rounding procedure.

Step 1 — Use the calculator square root key. Enter $17$ and press the $\sqrt{x}$ key to obtain the display value: $4.123105626\ldots$

Step 2 — Round to two decimal places. The hundredths digit is $2$ , and the digit to its right is $3$ . Since $3 < 5$ , the hundredths digit stays at $2$ . Drop all digits after the hundredths place.

Result: $\sqrt{17} \approx 4.12$

The approximation symbol $\approx$ is used because $4.12$ is a rounded value, not the exact square root of $17$ .
