Question

Simplify the radical expression.

1. √45

2. √180x^2

3.√490y^5 w^6

Answer 1

#1) 3√5
#2) 6x√5
#3) 7w^3y^2√10y

Answer 2

Answer with explanation:

`1. √(45)=√(3 * 3 * 5)\\\\=3 √(5)\\\\2. √(180 x^2)\\\\=√(3* 3 * 2 * 2 * 5 * x * x)\\\\=3 * 2 * x* √(5)\\\\=6 x √(5)\\\\3. √(490 y^5w^6)=√(7 * 7 * 2 * 5 * (y^2)^2* y * (w^3)^2)=7y^2w^3√(10 y)`
