Add two simple square roots: Compute √0.01 + √0.0064 and choose the correct sum.

Introduction / Context:The task is to add two exact decimal square roots. Each term is straightforward; accuracy depends on correct decimal placement.

Given Data / Assumptions:

• √0.01 and √0.0064 are both perfect decimal roots.
• We will compute each and add.

Concept / Approach:Recognize that 0.01 = 1/100 and 0.0064 = 64/10000. Then use square-root properties for fractions.

Step-by-Step Solution:

Verification / Alternative check:Square 0.08 to 0.0064 and 0.1 to 0.01; then add results as decimals.

Why Other Options Are Wrong:

• 0.3 and 0.03 are incorrect totals.
• √0.18 is not equal to 0.18; that is a different number (~0.4243).
• The correct numeric value 0.18 is not explicitly listed, hence “None of these.”

Common Pitfalls:Mistaking √0.18 for 0.18 or slipping a decimal place in 0.0064.

Final Answer:None of these
