Square Root of 17:4.123105625617661
Exponential Form:17^Ā½ or 17^0.5
Radical Form:ā17
Is the Square Root of 17 Rational or Irrational?
To understand why, letās delve into the definitions of rational and irrational numbers.
- Rational numbers are those that can be expressed as a fraction of two integers, where the denominator is not zero. In other words, they can be written in the form a/b, where a and b are integers and b is not equal to zero.
Examples of rational numbers include 1/2, -3, and 5.
- An irrational numbers cannot be expressed as a simple fraction of two integers. Their decimal representations are non-repeating and non-terminating.
Examples of irrational numbers include ā2, Ļ (pi), and ā3.
Square Root of 17 as Irrational:
- When we calculate the square root of 17, we find that it cannot be expressed as a fraction of two integers.
- Its decimal expansion, approximately 4.123105625617661, goes on infinitely without repeating a pattern.
To understand why the square root of 17 is irrational, let’s simplify it:
ā17 = ā(16 + 1) = ā16 * ā1 = 4 * ā1 = 4
Now, we know that 4 is a rational number. However, ā1 is famously rational. It cannot be represented as a fraction of two integers, and its decimal form goes on forever without repeating. Therefore, 4 is also irrational because the product of a rational number (4) and an irrational number (ā1) is always irrational.
In summary, the square root of 17 is irrational because it simplifies to a rational number (4), and when combined with the irrational ā1, the result is always irrational.
Method to Find Value of Root 17
To find the square root of 17, we can utilize various methods, including estimation, prime factorization, and using a calculator. Here’s a breakdown of a simple estimation method:
- Identify Perfect Squares Around 17: Recognize that the perfect square closest to but less than 17 is 16 (4Ā²=16), and the perfect square closest to but more than 17 is 25 (5Ā²=25).
- Estimation: Since 17 is between 16 and 25, its square root will be between 4 and 5.
- Refinement: For a more precise value, use a calculator or a square root table. The square root of 17 is approximately 4.123105625617661.
- Simplified Radical Form: The square root of 17 can also be expressed in simplified radical form as ā17=ā16Ć1=4ā1.
Square Root of 17 by Long Division Method
Finding the square root of 17 using the long division method involves the following steps:
Step 1: Preparation
Write 17 as 17.00 00 00, grouping digits in pairs from the decimal point. For 17, it looks like ā17ā.
Step 2: Find the Largest Square
Identify the largest square smaller than or equal to 17, which is 16 (4Ā²). Place 4 above the line as the first digit of the root.
Step 3: Subtract and Bring Down
Subtract 16 from 17 to get 1, then bring down the next pair of zeros to make it 100.
Step 4: Double and Find the Next Digit
Double the current result (4) to get 8. Now, find a digit (X) such that 48 multiplied by X is less than or equal to 100. Here, X is 2, because 482Ć2=96.
Step 5: Repeat with Precision
Subtract 96 from 100 to get 4, bring down the next zeros to get 400, then double the quotient (42) to get 84. Choose a digit (Y) so that 84Y multiplied by Y is just under 400.
Step 6: Finish at Desired Accuracy
Continue the process until reaching the desired level of accuracy. For the square root of 17, this method gives us about 4.123 as we extend the division
17 is Perfect Square root or Not
A perfect square root is a number that can be expressed as the product of an integer multiplied by itself. For example, 4 (2 Ć 2) and 9 (3 Ć 3) are perfect square roots.
However, when we examine 17, we find that it cannot be expressed as the product of two identical integers. There are no integers x such that x Ć x equals 17.
Therefore, 17 is not a perfect square root. It doesnāt have an integer square root. While it does have a square root (ā17), itās an irrational number and not the result of multiplying any whole number by itself.
