Answer for screen readers
The square root of 18000 is $60\sqrt{5}$.
Steps to Solve
- Factor the number 18000
To find the square root of 18000, we can start by factoring it into its prime components.
$$ 18000 = 18 \times 1000 = 18 \times 10^3 $$
Next, we can break down 18 and 1000:
$$ 18 = 2 \times 3^2 $$
$$ 1000 = 10^3 = (2 \times 5)^3 = 2^3 \times 5^3 $$
So, we have:
$$ 18000 = 2^1 \times 3^2 \times 2^3 \times 5^3 $$
- Combine the prime factors
Now we can combine the factors:
$$ 18000 = 2^{1+3} \times 3^2 \times 5^3 = 2^4 \times 3^2 \times 5^3 $$
- Calculate the square root
To find the square root, we take half of the exponents of the prime factors:
$$ \sqrt{18000} = \sqrt{2^4} \times \sqrt{3^2} \times \sqrt{5^3} $$
Calculating each term gives:
$$ \sqrt{2^4} = 2^2 = 4, \quad \sqrt{3^2} = 3, \quad \text{and} \quad \sqrt{5^3} = 5^{3/2} = 5 \sqrt{5} $$
So we can combine these together:
$$ \sqrt{18000} = 4 \times 3 \times 5\sqrt{5} $$
- Final multiplication and simplification
Now we multiply the numbers outside the square root:
$$ 4 \times 3 \times 5 = 60 $$
Therefore, our final answer can be expressed as:
$$ \sqrt{18000} = 60\sqrt{5} $$
The square root of 18000 is $60\sqrt{5}$.
More Information
The number 18000 can be thought of as a product of prime factors. By simplifying these factors, we were able to express the square root in a more manageable form. The use of prime factorization can be an effective strategy for finding square roots of large numbers.
Tips
- Not fully factorizing the number or missing some prime components.
- Forgetting to take half of the exponents when calculating the square root.
