2. √68

3. √60

4. √162

5. √3 x √6

5. √2 x √5

6. √4a^2

7. √9x^4

8. √300a^4

Answer 1

1. √28 = √(7*4) = 2√7

2. √68 = √(17*4) = 2√17

3. √60 = √(15*4) = 2√15

4. √162 = ?

5. √3 x √6 = √18 = √(9*2) = 3√2

5. √2 x √5 = √10

6. √(4a²) = 2a

7. √(9x⁴) = 3a²

8. √(300a⁴) = a²√(100*3) = 10a²√3

.

Answer 2

1. √28 = √4 x 7 = 2√7

2. √68 = √4 x 17 = 2√17

3. √60 = √4 x 15 = 2√15

4. √162 = √81 x 2 = 9√2

5. √3 x √6 = √18 = √9 x 2 = 3√2

6. √2 x √5 = √10

7. √4a² = √2a x 2a = 2a

8. √9x^4 = 3x²

9. √300a^4 = √100 x 3 x a^4 = 10√3a²

Hey, you have double 5s in your numbering, just to inform u ;)
