Essentially, a square root is the number that, when multiplied by itself, gives the original number. For example, the square root of 25 is 5, because 5 multiplied by 5 equals 25.
Introducing 729
Now, let's shift our focus to the number 729. This is what we call a perfect cube, meaning it is the result of multiplying 9 by itself three times (9 x 9 x 9). In mathematical terms, we can also express 729 as 9 raised to the power of 3.
The Symbol for Square Roots
When representing square roots, we use the symbol √ followed by the number inside the root. So, in this case, the square root of 729 is written as √729.
Simplifying the Calculation
In order to determine the square root of 729, we need to figure out the number that, when multiplied by itself, equals 729. We can simplify this calculation by breaking down 729 into its factors.
Simplifying through Prime Factors
One way to simplify the calculation is to break down 729 into its prime factors. Prime factors are factors that are prime numbers, meaning they can only be divided by 1 and themselves. For 729, the prime factors are 3 and 243.
Finding the Square Root
Once we have simplified 729 into its prime factors, we can look for pairs of factors that can be multiplied together to give 729. In this case, we have the pair of 3 and 243, and since 3 multiplied by 243 equals 729, we know that the square root of 729 is 27.
