Jawaban:

1. √300

=√100.3

=10√3

2. 3√5 + 2√5 – 2√20

= 3√5 + 2√5 – 2√4.5

=3√5 + 2√5 – 2.2√5

=3√5 + 2√5 -4√5

= 1√5 ( 1 nya boleh gk di tulis jd √5 ajaaa)

3. 10√980

=10√49.4.5

=10.7.2√5

=140√5

4. √63 – 3√7 + 2√28

=√9.7 – 3√7 + 2√4.7

=3√7 – 3√7 + 2.2√7

= 4√7

5. 5√300 + 3√40 -2√243 + √192

=5√100.3 + 3√4.10 – 2√81.3 + √64.3

= 5.10√3 + 3.2√10 – 2.9√3 + 8√3

=50√3 + 6√10 -18√3 + 8√3

= 40√3 + 6√10

6. √2 x √5 x √3

=√30

7. 5√2 (√2 – 2√3)

=5.2 – 10√6

= 10 – 10√6

8. (√7 + √3) (√7-√3)

=√49 – √21 + √21 -√9

=7-3

=4

9. (3√5 + 2√2)(2√5 -√2)

= 6.5 – 3√10 + 4√10 – 2.2

= 30 +√10 – 4

= 26 + √10

10. √3 x √3

=√9

=3
