tlong di jawab ya please....

c. 2√72 = 2√9x8 = 2x3√8 = 6√8
d. 4√54 = 4√9x6 = 4x3√6 = 12√6

1. akar 35
= akar 7 × akar 5

2. akar 12 / akar 9
= akar 4 / akar 3
= 2 / akar 3

3. 2 × akar 72
= 2 × akar 9 × akar 8
= 2 × 3 × akar 8
= 6 × akar 8

4. 4 × akar 54
= 4 × akar 9 × akar 6
= 4 × 3 × akar 6
= 12 × akar 6
