How do you find the root value of 169?
What Is the Square Root of 169?
- The square root of a number is the number that when multiplied to itself gives the original number as the product.
- 169 = a × a = a2
- Thus, a = √169 = √(13 × 13)
- 13 × 13 = 169 or -13 × -13 = 169.
- Thus the square root of 169 is +13 or -13.
- This shows that 169 is a perfect square.

What are the prime factors of the integer 18?
Prime factors of 18 are 2, 3×3. In number theory, the prime factors of a positive integer are the prime numbers that divide that integer exactly.
What are the prime factors of 18 Donuts?
Prime factors of 18 : 2, 3×3 In number theory, the prime factors of a positive integer are the prime numbers that divide that integer exactly. The prime factorization of a positive integer is a list of the integer’s prime factors, together with their multiplicities; the process of determining these factors is called integer factorization.
How to calculate the number of prime factors?
Start by testing each integer to see if and how often it divides 100 and the subsequent quotients evenly. The resulting set of factors will be prime since, for example, when 2 is exhausted all multiples of 2 are also exhausted. List the resulting prime factors as a sequence of multiples, 2 x 2 x 5 x 5 or as factors with exponents, 2 2 x 5 2 .
