What can divide 400?

Factors of 400: 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200 and 400.

How do you root 400?

What Is the Square Root of 400?

The square root of a number is the number that when multiplied to itself gives the original number as the product.
400 = a × a = 202
Then a = √400 = √(20 × 20)
20 × 20 = 400 or -20 × -20 = 400.
The 2nd root of 400 is +20 or – 20.
This shows that 400 is a perfect square.
