Calculating the Square Root of 43,560

The square root of a number is a value that, when multiplied by itself, gives the original number. To find the square root of 43,560, several methods can be employed, including estimation, prime factorization, or using a calculator for precision.

Mathematically, the square root of 43,560 is represented as:

√43,560

Estimation Method

Given that 200² = 40,000 and 210² = 44,100, the square root of 43,560 lies between 200 and 210. Since 43,560 is closer to 44,100 than to 40,000, the square root will be nearer to 210.

Prime Factorization Method

Breaking down 43,560 into its prime factors can help determine the square root more precisely.

  • Start by dividing 43,560 by small prime numbers:
Step Division Quotient Prime Factor
1 43,560 ÷ 2 21,780 2
2 21,780 ÷ 2 10,890 2
3 10,890 ÷ 2 5,445 2
4 5,445 ÷ 3 1,815 3
5 1,815 ÷ 3 605 3
6 605 ÷ 5 121 5
7 121 ÷ 11 11 11
8 11 ÷ 11 1 11

Thus, the prime factorization is:

43,560 = 2³ × 3² × 5 × 11²

Simplifying the Square Root Using Prime Factors

To simplify the square root, pair the prime factors:

  • 2³ = 2² × 2¹ → one pair of 2s and one leftover 2
  • 3² = (3 × 3) → one pair of 3s
  • 5¹ → no pair
  • 11² = (11 × 11) → one pair of 11s

Extract the pairs from the square root:

√43,560 = √(2² × 2¹ × 3² × 5 × 11²)

= (2 × 3 × 11) × √(2 × 5)

= 66 × √10

Since √10 ≈ 3.1623,

√43,560 ≈ 66 × 3.1623 = 208.65 (rounded to two decimal places)

Verification with Calculator

Using a scientific calculator to verify:

Expression Result
√43,560 ≈ 208.665

This confirms the approximate value derived through prime factorization.
