tolong bantu kerjain huruf A sampai J ya guys please

1. 4√3 x 2√3 = (4 x 2)√3
                    = 8√3

2. √2 (√3 + √5) = (√2 x √3) + (√2 x √5)
                         = √6 + √10

3. √2 (√3 x √5) = √2 x (√15)
                        = √30

4. 2√3 (√3 - √5) = 2√3 x √3 - 2√3 x √5
                          = 2 x 3 - 2√15
                          = 6 - 2√15

5. 2√3 x 4√2 x 3√5 = (2 x 4 x 3)(√3 x √2 x √5)
                              = 24√30

6. (2 +√3)(2 - √3) = 4 - 2√3 + 2√3 - √9
                             = 4 - 3
                             = 1

7. (√2 + √5)(√2 +√5) = √4 + √10 + √10 + √25
                                = 2 + 5 + 2√10
                                = 7 + 2√10

8. (√2 - √7)(√2 - √7) = √4 - √14 - √14 + √7^2
                                 = 2 + 7 - 2√14
                                 = 9 - 2√14

9. (3 - √2)(3 - √2) = 9 - 3√2 - 3√2 + √4
                             = 9 + 2 - 6√2
                             = 11 - 6√2

10. (2√2 +√3)(2√2 + √3) = 4√4 + 2√6 + 2√6 + √9
                                       = 4(2) + 9 + 4√6
                                       = 8 + 9 + 4√6
                                       = 17 + 4√6

Semoga Dapat Membantu,,,,
