The square root of any prime number
WebLet n = 491. How many prime numbers are less than or equal to the square root of n? Let n = 43. Write a list of all the prime numbers less than or equal to Vn. (Enter your answers as a comma-separated list.) Suppose n is a fixed integer. Let S be the statement, 'o is not divisible by any prime number less than or equal to Vn." WebSolution. Verified by Toppr. Let p be a rational number and. p= ba. ⇒p= b 2a 2. ⇒a 2=pb 2. ∴p divides a 2. But when a prime number divides the product of two numbers, it must divide atleast one of them. here a 2=a×a.

WebSimplified Radical Form of Square Root of 20. 20 is not a prime number. Thus it has more than two factors, 1, 2, 4, 5, 10 and 20. To find the square root of any number, we take one number from each pair of the same numbers from its prime factorization and we multiply them. The factorization of 20 is 2 × 2 × 5 which has 1 pair of the same number.
