Answer for screen readers
The simplified form of the square root of 164 is $2\sqrt{41}$.
Steps to Solve
-
Identify the prime factorization of 164
First, we need to determine the prime factors of 164. We start by dividing by the smallest prime number, which is 2:
$$ 164 \div 2 = 82 $$
Next, we divide 82 by 2:
$$ 82 \div 2 = 41 $$
Since 41 is a prime number, the complete prime factorization of 164 is:
$$ 164 = 2^2 \times 41 $$ -
Identify the largest perfect square
From the prime factorization, we see that $2^2$ is a perfect square. Thus, the largest perfect square that divides 164 is $2^2 = 4$. -
Rewrite the square root in simplified form
We can now express $\sqrt{164}$ using the largest perfect square:
$$ \sqrt{164} = \sqrt{4 \times 41} $$
Using the property of square roots, we simplify this to:
$$ \sqrt{164} = \sqrt{4} \times \sqrt{41} $$ -
Calculate the square root of the perfect square
Now we can find the square root of 4:
$$ \sqrt{4} = 2 $$
Thus, we have:
$$ \sqrt{164} = 2 \times \sqrt{41} $$
The simplified form of the square root of 164 is $2\sqrt{41}$.
