19044 Is a Perfect Square
19044 = 138², so √19044 = 138.
Formula
To rewrite any square root in simplest radical form:
√(a2 · b) = a · √b
Where:
- a2 = the largest perfect-square factor of the radicand (the number under the √ symbol)
- b = the remaining squarefree factor (no perfect square divides it other than 1)
Worked example for √72:
- 72 = 36 × 2 = 62 × 2
- So a2 = 36, a = 6, b = 2
- Therefore √72 = 6√2
How to Simplify Square Roots
Simplifying a square root means rewriting it in the simplest radical form, where the number under the radical (the radicand) has no perfect square factors other than 1.
Method: Prime Factorization
- Find the prime factorization of the radicand.
- Identify pairs of identical prime factors.
- Each pair contributes one factor outside the radical.
- Any unpaired prime factor stays under the radical.
Example: Simplify √72
- 72 = 2 × 2 × 2 × 3 × 3 = 23 × 32
- We have a pair of 2's, a pair of 3's, and a leftover 2.
- Pair of 2's → contributes one 2 outside. Pair of 3's → contributes one 3 outside. Leftover 2 stays inside.
- √72 = (2 × 3)√2 = 6√2
