Let's go through the questions one by one.
Question 5:
When expanded \( 3^2 \) becomes
Question Blank 1 of 2:
\( 3 \times 3 \)
and when evaluated, it is equal to
Question Blank 2 of 2:
\( 9 \).
Question 6:
When expanded \( 5^2 \) becomes
Question Blank 1 of 2:
\( 5 \times 5 \)
and when evaluated, it is equal to
Question Blank 2 of 2:
\( 25 \).
Question 7: Fill in the blanks with square root or principal square root.
The Question Blank 1 of 7:
square root
of a number is a value that when the value is multiplied by itself, the product (answer) equals the original number.
For example, because \( 12 \times 12 \) is equal to \( 144 \), the square root of Question Blank 2 of 7:
144
is Question Blank 3 of 7:
12.
We use \( \sqrt{} \) to find the square root of numbers. It is called the Question Blank 4 of 7:
square root
symbol.
Question Blank 5 of 7:
√144 is equal to 12.
📌 \( 144 \) also has another square root, and it's -12 because -12 times itself is also equal to \( 144 \).
But the principal square root is the Question Blank 6 of 7:
principal
square root of a number.
For example, to find the square root of \( 25 \) we do \( 5 \times 5 \). We will end up with two answers because \( 5 \times 5 \) equals \( 25 \) and so does \(-5 \times -5\). Because of this \( 5 \) and \(-5\) are both square roots of \( 25 \). However, the principal square root of \( 25 \) is Question Blank 7 of 7: 5.
I hope this helps! Let me know if you have further questions.
