Significant Figure Rules for Square Roots

When calculating square roots, the number of significant figures in the result depends on the original number's significant figures:

• For numbers with an exact integer square root (like 16 or 25), the result inherits all significant figures from the original number
• For numbers without an exact integer square root, the result has one more significant figure than the original number
• Trailing zeros in the original number that are not significant (like in 100) do not affect the square root's significant figures

Examples of Square Root with Significant Figures

Let's look at some examples to understand how significant figures work with square roots:

Notice how exact integer square roots preserve all significant figures from the original number, while other square roots add one more significant figure.

Common Mistakes to Avoid

When working with significant figures in square roots, these common errors can lead to incorrect results:

• Assuming all trailing zeros are significant (they often aren't unless specified)
• Forgetting to add an extra significant figure for non-integer square roots
• Rounding the original number before calculating the square root
• Ignoring the rules when the original number has a decimal point
