To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: A square root of a number is a value that, when multiplied by itself, gives the original number. Here, we want such that .
Step 2: We test integer values to find which one squared equals 36. Testing and gives:
-
-
-
-
-
-
Step 3: The integer satisfies . Therefore, .
Step 4: The correct choice from the given answer choices is 6 (Choice 4).
Hence, the square root of 36 is .
6
\( \sqrt{36}= \)
When you multiply your answer by itself and get the original number! For example, since , we know .
It helps! Start with these common ones: , , , , , . Practice makes them automatic!
Then the answer won't be a whole number. For example, is between 5 and 6, but it's not exactly either one. You'd need a calculator for the exact decimal.
The radical symbol means the principal (positive) square root by definition. While both 6 and -6 when squared equal 36, specifically means the positive answer: 6.
Yes! Look at the last digit of the number. For example, numbers ending in 6 (like 36) have square roots ending in 4 or 6. This can help you guess and check more efficiently.
