The root sign is a mathematical symbol. The root sign is a symbol used to represent the root operation of a number or an algebra. If a? =b, then A is the n-th root of B or A is the 1/n power of B. The n-th handwritten and printed characters are represented by, and the number of roots or algebraic expressions are written in the area surrounded by the left side of the symbol and the right side of the horizontal part above the symbol, which cannot be out of bounds.

3√ 18-√32=9√2-4√2=5√2

5√32-√200=20√2- 10√2= 10√2

2√27+3√3-√ 12=6√3+3√3-2√3=7√3

2√20-√45+√500= 4√5-3√5+ 10√5= 1 1√5

Simplify or something:

(√ 3-√ 2) (√ 3+√ 2) = 3-2 = 1 (square difference formula)

(√3-√2)(√3-√20)= 3-√2*√3-√20*√3+√2*√20=3-√6-2√ 15+2√ 10

(√ 5-√ 3) (√ 5-√ 3) = 5+3-2 √15 = 8-2 √15 (complete variance)

(2 √ 5+ 1) (√ 5- 1) = (√ 5+ 1)+√ 5- 1 = 5- 1+√ 5-.

(4 √ 5- 1) (2 √ 5- 1) = (2 √ 5- 1) = 10+ 1-.

(√11-3) (√11+3) =1-3 = 8 (square difference).
