400 is a perfect square and divides 6400

1600 is a perfect square and divides 6400

6400 is a perfect square and divides 6400

**Step 3: Divide To Perfect Square**

Divide 6400 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 6400 in its simplest form: 80√1

## How do you simplify √6400

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 6400. Divide 6400 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 80√1*.
