Is the Square Root of 149 Rational or Irrational?

The square root of 149 is irrational.

The square root of 149 is an irrational number because it cannot be expressed as a fraction of two integers. Its decimal expansion is non-terminating and non-repeating. Therefore, it falls into the category of irrational numbers.

Rational Number:
A rational number is any number that can be expressed as a fraction, where both the numerator and denominator are integers, and the denominator is not zero. It is typically denoted in the form ( \frac{a}{b} ). Examples include 3/4, -5/2, 0, 1, and -2. For instance, 3/4 qualifies as a rational number because it consists of integers as its numerator and denominator, with the denominator being non-zero.

Irrational Number:
An Irrational number is a number that cannot be represented as a simple fraction of two integers. Its decimal representation is both non-terminating and non-repeating. Notable examples include ( √2 ), ( π ) (π), and ( \π ) (π). For instance, ( √2 ) is irrational because its decimal expansion (approximately 1.41421356…) continues indefinitely without exhibiting any repetitive pattern.

Square Root of 149 by Long Division Method

Calculating the Square Root of 149 Using Long Division Method

Digit Pairing: Begin by grouping the digits of 149 into pairs from the right: 49 and 1.

Finding Initial Quotient: Determine a number (N) whose square is ≤ 1. Since 1 × 1 = 1, N is 1. This gives us the initial quotient.

New Divisor: Double the initial divisor (N) to obtain the new divisor (2N = 2).

Dragging Down the Next Pair: Bring down the next pair of numbers (049) to form the new dividend.

Determining the Next Digit: Find a number (q) such that 2q × q ≤ 49. The value of q is 2.

Decimal Placement: Place a decimal point in both the dividend (at the end of 149) and the quotient (at the end of 12). Additionally, append three pairs of zeros to the dividend after the decimal.

Repeat Steps: Continue the process for the remaining three pairs of zeros.

Final Result: The square root of 149 is approximately 12.206 when calculated using the long division method.
