Carilah himpunan penyelesaian dari pertidaksamaan-pertidaksamaan berikut

√(x-4) < 3
(√(x-4)²) < 3²
x - 4 < 9
x < 9+4
x < 13

hp = {.....,10,11,12}

12. √x-4 > 3
= (√x-4)² > (3)²
= x - 4 > 9
= x > 9+4
= x > 13

Hp = {x >13}

13. √x-4 < 3
= (√x-4)² < ( 3 )²
= x -4 < 9
= x < 9 + 4
x < 13

Hp {x<13}

14. √2x-4 ≤ √x-3
(√2x-4)² ≤ ( √x-3 )²
2x -4 ≤ x-3
2x -x ≤ -3 + 4
x ≤ 1

Hp = { x ≤1}
