Retail | How To REVIEWED BY: Meaghan Brophy Meaghan has provided ...Which means the right side must be even too: a^2 is even. But if the square of a number is even, then that number itself is even too. So a is even. If a is even, we can write it as a multiple of 2: a = 2c for some c. Plug this into the equation above: 6b^2 = a^2 = (2c)^2 = 4c^2. Divide both sides by 2: 3b^2 = 2c^2.Step 1: Find the largest number whose square is less than or equal to the number 68. Take this number as the divisor and the quotient (8 in this case). Divide and write the remainder. Step 2: In the quotient, put a decimal point after 8. Bring down two zeroes to the right of the remainder. So, the new dividend is 400.Let us understand the process of finding square root of 71 by long division. Step 1: Pair the digits of 71 starting with a digit at one's place and put a horizontal bar to indicate pairing. Step 2: Now we find a number which on multiplication with itself gives a product of less than or equal to 71. As we know 8 × 8 = 64 < 71.Square Root of 5. The square root of 5 is expressed as √5 in the radical form and as (5) ½ or (5) 0.5 in the exponent form. The square root of 5 rounded up to 5 decimal places is 2.23607. It is the positive solution of the equation x 2 = 5. Square Root of 5: 2.23606797749979.Welcome to "What are Square Roots?" with Mr. J! Need help with square roots?
