WebSquare root. A square root is a number that can be multiplied by itself to give us the value under the radical symbol (also referred to as the radix). A square root is denoted as follows: In the figure above, z is the square root of x. We can also write this as "z raised to the power of 2 is equal to x" as follows: z 2 = x.

WebThe square root of a number is the factor that we can multiply by itself to get that number. The symbol for square root is 1 . Finding the square root of a number is the opposite of squaring a number. Example: 4 × 4 or 4 2 = 16. So 16 = 4. If the square root is a whole number, it is called a perfect square!

WebThere is a fun method for calculating a square root that gets more and more accurate each time around: a) start with a guess (let's guess 4 is the square root of 10) b) divide by the guess (10/4 = 2.5) c) add that to the guess (4 + 2.5 = 6.5) d) then divide that result by 2, in other words halve it. (6.5/2 = 3.25)
