## Methods to Find Value of Root 162

Method 1: Estimation and Trial-and-Error

• Estimate:
Since ( 162 ) is between ( 144 ) and ( 169 ), which are the squares of ( 12 ) and ( 13 ) respectively, we know that √162 is between (12) and ( 13 ).
• Trial-and-Error:
Test values between ( 12 ) and ( 13 ) to refine the estimate.
12.5² = 156.25 (too low)
12.6² = 158.76 (too low)
12.7² = 161.29 (very close)
12.8² = 163.84 (too high)
• Conclusion:
√162 is approximately ( 12.7 ).

Method 2: Long Division

• Set up long division:
• Find the square root digit by digit:
Follow the long division process to find the square root of ( 162 ) to the desired precision.

Method 3: Newton’s Method (Iterative)

• Initial Guess: Start with an initial guess ( x₀ ) close to the actual value of √162, for example, ( x₀ = 12 ).
• Iterative Calculation: Use the iterative formula ( xₙ₊₁} = 1/2( xₙ + 162/xₙ) to successively improve the approximation.
• Repeat: Continue iterating until the desired level of precision is reached.

## Square Root of 162 by Long Division Method

Step 1: Find a number (n) which when multiplied with itself (n × n ≤ 1). So, (n) will be (1) since (1 ×1 = 1).

Step 2: Now, we get the quotient as (1). Also, we have to add the divisor (n) with itself to get the new divisor. The new divisor here will be (2).

Step3: Bring down the pair (62). So, our new dividend is (62). Now find a number (m) such that (2m× m≤ 62). The number (m) will be (2) as (2²×2 = 4× 2 = 8 ≤ 62).

Step 4: Add a decimal in the dividend and quotient part simultaneously. Also, add 3 pairs of zero in the dividend part.

## 162 is Perfect Square root or Not

No, 162 is not a perfect square number.

A perfect square is a number that can be expressed as the product of an integer multiplied by itself. In other words, perfect squares are the squares of integers. For example, ( 9 ) is a perfect square because ( 3 × 3 = 9 ).

## What are the square factors of 162?
