What is the factorization method of 20? ›
Factorisation is the process of reducing the bracket of a quadractic equation, instead of expanding the bracket and converting the equation to a product of factors which cannot be reduced further. For example, factorising (x²+5x+6) to (x+2) (x+3). Here, (x+2) (x+3) is factorisation of a polynomial (x²+5x+6).
What is the prime factorization and exponents of 20? ›
The prime factorization of 20 using exponents is 2 2 ∗ 5 . First, we create the prime factorization for 20. Once we have the prime factorization, which is 2*2*5, we can group like factors. Finally, we write the number of times a factor repeats as its exponent.
What is the prime factorization method of root 20? ›
The prime factorization method is written as a square root of a non-perfect square number in the simplest radical form. For example: 20 = 2 × 2 × 5. So, √20 = √2 × 2 × 5 = 2√5.
