Cómo Encontrar La Raíz Cuadrada De Un Número Estudyando For this example we will find the square root of 661062. step 1: use your knowledge of square numbers to find the first two digits of the answer. for 661062, we see that 81² = 6561 < 6610 < 82² = 6724, so the first two digits are 81. all divisions in step 3 and onward will use these first two digits. step 2:. Calculate the difference between guess² and the number you want to square root. for example, 82– 59.6 = 4.4. divide it by twice your original guess. here, 4.4 ÷ (2 × 8) = 4.4 ÷ 16 = 0.275. this is your correction. add or subtract the correction from the guess to get the estimate of 8– 0.275 = 7.725. Now find the square root of 16 which is 4. now 4 is our whole number of the answer. take the difference between 18 and 16 and the answer is 2. step 1 gives us the whole number of our answer and the step 2 and 3 give us the fraction. fraction is 2 8 which means 0.25. now add it to the whole number and the answer is 4.25. If you know that the number has an exact (integral) square root, there are lots of mental tricks that apply to different situations. for 2601, i first noted that 2 6 0 1 = 9, which means it is divisible by 9, so its square root must be divisible by 3. 2601 is a bit bigger than 2500, and i know its square root is 50.

Square Root 1 To 10 Now find the square root of 16 which is 4. now 4 is our whole number of the answer. take the difference between 18 and 16 and the answer is 2. step 1 gives us the whole number of our answer and the step 2 and 3 give us the fraction. fraction is 2 8 which means 0.25. now add it to the whole number and the answer is 4.25.

Write 7 in the numerator and 8 in the denominator of the fraction that we are going to append to 4. \ (\sqrt {23} = 4.79583152331 \approx 4\frac {7} {8} = 4.875\) our approximation 4.875 is close to 4.7958! you can literally do this in your head without using a calculator for the square root of any positive integer. First group the numbers under the root in pairs from right to left, leaving either one or two digits on the left (6 in this case). for each pair of numbers you will get one digit in the square root. square the 2, giving 4, write that underneath the 6, and subtract. bring down the next pair of digits.
