The original number who square is 72 is the square root of 72. Can you discover what is the number? It can be seen that there are no integers who square provides 72.

72 = 8.4852

To inspect this answer, we can discover (8.4852)2 and we have the right to see that we obtain a number 71.99861904. This number is really close come 72 when that rounded to its nearest value.

Any number i m sorry is either end or non-terminating and has a repeating pattern in its decimal part is a rational number. We experienced that 72 = 8.48528137423857. This decimal number is non-terminating and the decimal component has no repeating pattern. So it is no a reasonable number. Hence, 72 is one irrational number.

Important Notes:

72 lies between 64 and 81. Hence, 72 lies in between 64 and 81, i.e., 72 lies in between 8 and 9.Square source of a non-perfect square number in the simplest radical type can be discovered using element factorization method. For example: 72 = 2 × 2 × 2 × 3 × 3. So, 72 = (2 × 2 × 2 × 3 × 3) = 62.

How to discover the Square source of 72?

There room different methods to find the square source of any number. Us can find the square root of 72 utilizing long division method.Click here to know much more about it.

Simplified Radical kind of Square source of 72

72 is a composite number. Hence factors that 72 are 1, 2, 3, 4, 6, 8, 9 12, 18, 24, 36, and 72. Once we find the square root of any number, us take one number from every pair that the very same numbers indigenous its element factorization and we main point them. The administer of 72 is 2 × 2 × 2 × 3 × 3 which has actually 1 pair of the exact same number. Thus, the simplest radical type of √72 is 62.

Square root of 72 by Long department Method

The square root of 72 can be uncovered using the long department as follows.

Step 1: In this step, we pair turn off digits that a provided number beginning with a digit at one"s place. We placed a horizontal bar come indicate pairing.Step 2: Now we require to find a number which on squaring offers value less than or same to 72. As we know, 8 × 8 = 64 Step 3: Now, we have actually to bring down 00 and also multiply the quotient by 2 which offers us 16. Step 4: 4 is written at one"s ar of brand-new divisor because when 164 is multiply by 4, 656 is derived which is much less than 800. The derived answer currently is 144 and we lug down 00.Step 5: The quotient is now 84 and it is multiply by 2. This gives 168, which then would become the beginning digit the the new divisor.Step 6: 7 is written at one"s ar of brand-new divisor because when 1688 is multiply by 8, 13504 is derived which is much less than 14400. The acquired answer currently is 896 and also we bring down 00.Step 7: The quotient is now 848 and it is multiply by 2. This gives 1696, which then would become the beginning digit the the brand-new divisor.Step 8: 5 is written at one"s place of new divisor due to the fact that when 16965 is multiplied by 8, 84825 is obtained which is much less than 89600. The derived answer currently is 4775 and we carry down 00.


So far we have acquired 72 = 8.485. On repeating this process further, us get, 72 = 8.48528137423857

Are -72 and -72 same ?Is -72 a genuine number? 

Example 2: Is the radius the a circle having actually area 72π square inches same to size of a square having area 72 square inches? 


Radius is found using the formula the area that a one is πr2 square inches. By the offered information,

πr2 = 72π r2 = 72

By taking the square root on both sides, √r2= 72. We recognize that the square source of r2 is r.The square source of 72 is 8.48 inches.

The size of square is uncovered using the formula the area that square. Together per the provided information,

Area = length × lengthThus, size = √Area = 72 = 8.48 inches

Hence, radius of a circle having area 72π square inches is same to the length of a square having area 72 square inches.
