Exponential Form: 800^1/2 or 800^0.5
Radical Form: √800
Is the Square Root of 800 Rational or Irrational?
Rational Numbers: Rational numbers are expressible as fractions of two integers.
Irrational Numbers: Irrational numbers cannot be expressed as fractions of integers.
As the square root of 800 is not a perfect square, it is irrational. It cannot be expressed as a simple fraction.
Methods to Find the Value of Root 800
- Estimation Method: Begin with an initial approximation and refine it iteratively using methods like Newton-Raphson.
- Prime Factorization Method: Express 800 as a product of prime factors, then find the square root of each prime factor.
- Calculator: Utilize a calculator with a square root function to directly compute the square root of 800.
Square Root of 800 by Long Division Method
Step 1: Starting from the right, pair up the digits of 800 by placing a bar above 00 and 8 separately. Also, pair the 0s in the decimal part in pairs of 2 from left to right.
Step 2: Find a number that, when multiplied by itself, gives a product less than or equal to 8. This will be 2, so place 2 in the quotient and the divisor’s place, resulting in a remainder of 4.
Step 3: Drag down 00 beside the remainder, making it 400. Add the divisor to itself and write it below (2 + 2 = 4).
Step 4: Find a number X such that 4X × X results in a number less than or equal to 400. The number 8 works here, so place 8 next to the divisor and in the quotient, making the new divisor 48.
Step 5: Find the remainder and drag down the pair of 0s from the decimal part of the number. Add X to the divisor, making the new divisor 56.
Continue in this manner to get the desired decimal places.
800 is a Perfect Square or Not
800 is not a perfect square because it cannot be expressed as the product of an integer multiplied by itself. In other words, there is no integer such that its square equals 800.
