What is the fastest way to find the square root?

Example: Find the square root of 40401.

  1. Step 1: Pair the digits from right to left, 404 01.
  2. Step 2: Check the unit digit of the number and compare it with the above table.
  3. Step 3: Now, the first three digits are 404.
  4. Step 4: Hence, the required square root is 201.

How do you find a square in ten seconds?

Find Square of any number within 10 seconds

  1. 325 = 3_25 => 3.
  2. Square the number from Step 1: 32 = 9.
  3. Divide the number from Step 1 by 2: 3/2 =1.5.
  4. Add Step 2 and Step 3 : 9 + 1.5 = 10.5.
  5. Multiply the number from Step 4 by 10: 10.5 * 10 =105.
  6. Write the number 625 next to the result from Step 5: 105_625 = 105625.

How do you find square root without a calculator?

Try it: +2 × +2 = 4 and -2 × -2 = 4. Since a square root of a number must equal that number when multiplied by itself. When you multiply this number by itself, and set it up as a full equation ( n * n = x ), the two factors (n and n) are either both positive or both negative since they are the same number.

How do you calculate square root by hand?

Long division method

  1. Separate your square root base into pairs.
  2. Find the largest square that divides into the first number or pair.
  3. Subtract the square from the first number or pair.
  4. Drop down the next pair.
  5. Multiply the first digit of the square by two.
  6. Set up the next factor equation.

How do you find the square root without a calculator?

Let us see some examples to find the square root using prime factorisation.

  1. Square root of 400. By prime factorisation, we get; 400 = 2 x 2 x 2 x 2 x 5 x 5. Now pairing the common numbers in a pair of two, we see here three pairs.
  2. Square root of 121. By prime factorisation, we get: 121 = 11 x 11.
  3. Square root of 169.

How do you calculate fast in math?

For easy and fast mental math calculations, you should add or subtract from the left to the right. For example, adding 340 + 215 will quickly give you the answer: 555. In case of carrying forward numbers, just add it to the digit before them, like 340 + 285 = 625.
