Is the Square Root of 625 Rational or Irrational?

The square root of 625 is rational number

Rational Number:

The square root of 625 is rational. A rational number is defined as a number that can be expressed as the fraction 𝑝𝑞​, where 𝑝 and 𝑞 are integers and 𝑞 is not zero. In this case, √625=25, which can be expressed as 25/1​, satisfying the conditions for rational numbers. Since 25 is a whole number, it clearly fits the definition of a rational number.

Irrational Number:

A number is considered irrational if it cannot be expressed as a simple fraction 𝑝𝑞 where both 𝑝 and 𝑞 are integers and 𝑞 is not zero. Irrational numbers have non-repeating, non-terminating decimal expansions. An example is √2​, which approximates to 1.41421356… and continues indefinitely without repeating. However, since √625=25 is a terminating decimal and can be expressed as a fraction, it is not irrational.

Methods to Find the Value of Root 625

Finding the square root of 625 can be done using various methods. Here are some methods are as follows:

1. Prime Factorization

  • Decompose 625 completely into its prime factors.
  • Since 625=5×5×5×5=54
  • Group the factors in pairs: (5×5)×(5×5)=25×25
  • The square root of 625 is 25.

2. Using a Calculator

  • This is the simplest and most direct method; simply input 625 into a calculator and press the square root function to obtain 25.

3. Estimation

  • By knowing the squares close to 625 (such as 20²=400 and 30²=900), you can estimate that the square root of 625 lies between 20 and 30.
  • Checking squares around the midpoint, such as 25², confirms that 25 is the square root.

4. Exponent Rules

  • Recognizing 625 as 5 and applying exponent rules ( √𝑥²​=x),
  • The even exponent 4 allows simplification using the rule √𝑎ᵇ=𝑎ᵇ/² giving 5⁴/²=5²​=25

These methods provide various ways to determine the square root of 625, each suited to different situations and levels of mathematical familiarity.

Square Root of 625 by Long Division Method

To find the square root of 625 using the long division method, follow these steps:

  1. Pair the digits: Start by writing the number 625. Here, you only need to handle the three digits, so you pair them as 6, 25 from right to left.
  2. Find the largest square: Look for the largest square less than or equal to the first pair or digit on the left, which is 6. The largest perfect square less than 6 is 4 (22), so place 2 as the divisor above the first pair.
  3. Subtract the square: Subtract 4 from 6, leaving a remainder of 2. Bring down the next pair of digits (25), making the number now 225.
  4. Double the quotient: The initial quotient is 2. Double this to make 4. Place it beside the remainder to form a new dividend of 225.
  5. Find the next digit: Find a digit 𝑋 that fits in the equation 40𝑋≤225 such that (20𝑋+𝑋)2≤225. 𝑋 will be 5, because 45×5=225.
  6. Complete the calculation: Place 5 beside 2 in the quotient area, making the quotient 25. Subtract 225 from 225 to get a remainder of 0.
