Is the Square Root of 117 Rational or Irrational?
A number is considered irrational if it cannot be expressed as a simple fraction (i.e., as the ratio of two integers). The square root of 117 cannot be expressed this way, and its decimal representation is non-repeating and non-terminating: approximately 10.816653826391969. Therefore,√117 is an irrational number.
A rational number is any number that can be expressed as the quotient or fraction of two integers, where the denominator is not zero. Rational numbers include fractions, integers, and terminating or repeating decimals.
Methods to Find Value of Root 117
Prime Factorization Method:
Decompose 117 into its prime factors: (117 = 3× 3×13).
Pair the prime factors in groups of two: (3 ×3 = 9) (one pair).
Since 13 is left alone, it remains outside the square root.
Thus, √117= = 3√13.
Estimation Method:
Find perfect squares close to 117: (11² = 121) and (10² = 100).
Since 117 is closer to 121 than 100, you can estimate the square root of 117 to be between 10 and 11.
A closer estimation can be found using averages: (10=+11)/2= 10.5.
Use 10.5 as a starting point for iterative methods like Newton’s method or the Babylonian method.
Iterative Methods:
Newton’s Method: Use the formula (xₙ₊₁ = 1/2 (xₙ + 117/xₙ) with an initial guess. Repeat until convergence.
Babylonian Method: Use the formula (xₙ₊₁ = 1/2 (xₙ + 117/xₙ)) iteratively until the value converges to the square root of 117.
Using a Calculator or Computer:
Most calculators and computers have built-in functions to calculate square roots directly. Simply input 117 and find the square root.
Square Root of 117 by Long Division Method
Step 1: Begin by pairing the digits of 117 from right to left. Place a horizontal bar to indicate the pairs. Since 117 has two digits, we have one pair, 17, and a single digit 1.
Step 2: Find a number that, when multiplied by itself, gives a product less than or equal to 1. We know (1 × 1 = 1).
Step 3: Multiply the quotient (initially 0) by 2. This gives us 2, which becomes the starting digit of the new divisor.
Step 4: Place 0 at the units place of the new divisor, resulting in 20. Multiply 20 by 0 to get 0. The answer is now 1, and we bring down 00.
Step 5: Multiply the quotient (now 10) by 2. This gives 20, the starting digits of the new divisor.
Step 6: Place 8 at the units place of the new divisor (208) because (208 × 8 = 1664). The remainder obtained is 36, and we bring down 00.
Step 7: Multiply the quotient (now 108) by 2. This gives 216, the starting digits of the new divisor.
Step 8: Place 1 at the units place of the divisor (2161) because (2161×1 = 2161). The answer obtained is 1439. Next, bring down the next pair of numbers, 00.
Step 9: Multiply the quotient (now 1081) by 2. This gives 2162, the starting digits of the new divisor.
Step 10: Place 6 at the units place of the divisor (21626) because (21626× 6 = 129756). The remainder obtained is 14144. Continue these steps until achieving the desired number.
Is 117 Perfect Square root or Not
A perfect square is a number that can be expressed as the product of an integer multiplied by itself. Since there is no integer ( n ) such that ( n×n = 117 ), 117 is not a perfect square.
