2√218 is in the lowest radical form.

Simplified Radical Form of √872

One of the main facts used to simplify square roots is that the square root of a product is equal to the product of square roots: √(x×y) = √x×√y

Explanation:

When we find square root of any number, we take one number from each pair of the same numbers from its prime factorization and we multiply them.

Step 1: List Factors

To simplify √872, we need to divide into factors.

√872 = √2 x √2 x √2 x √109

Step 2: List Perfect Squares

1 is a perfect square and divides 872
4 is a perfect square and divides 872

Step 3: Divide To Perfect Square

Divide 872 by the largest perfect square you found in the previous step:

Step 4: Calculate The Square Root

Calculate the square root of the largest perfect square:

Final Step :

Put Steps 3 and 4 together to get the square root of 872 in its simplest form: 2√218

How do you simplify √872

The general approach is to first check if it is a perfect square. If so, you have the answer. If it is not a perfect square, see if any of its factors are perfect squares, or can be combined to make square numbers.

Find the lowest prime number that can divide 872. Divide 872 repeatedly using the long division method till you reach 1.

A pair of factor 'twins' under a square root sign (radical) form a single factor outside of it.

Factors that do not have a twin remain under the radical. Multiply them back together and leave them in there.

So, the answer is 2√218.

Simplified Decimal Form of √872
