Which of the following is the square root of 0.01 ? \( \begin{array}{lll}\text { (a) } 0.01 & \text { (b) } 0.1 & \text { (c) } 0.001\end{array} \)

The square root of 0.01 is 0.1, because \(0.1 \times 0.1 = 0.01\). It's like finding a number that, when multiplied by itself, takes you back to the original number—like retracing your steps to find where you started! A fun trick to remember this is to think about the decimal places. Since 0.01 has two decimal places, its square root will have half that number of decimal places—so you end up with 0.1, which has one decimal place. It’s like dividing the decimals in half!
