Step 1: Let's recall what is a square root.
When we calculate a square root, we are calculating a number that when multiplied by itself gives the original number.
The notation is √
Step 2: Let's give some examples:
• √4 = 2 because 2 * 2 = 4
,
• √9 = 3 because 3 * 3 = 9
,
• √16 = 4 because 4 * 4 = 16
Step 3: As we can see in the exercise, we have four square roots:
√37, √35, √38 and √30
What do these values have in common?
If we analyze carefully, they are close to a perfect square root:
