d) √13+ ⁴√(12 - x) = 4
(⁴√(12 - x))⁴=(4-√ 13)⁴
12 - x= (4-√13)² (4-√13)²
12-x=(16-8√13+13) (16-8√13+13)
12-x=16.16-2.16.8√13+2.16.13-2.13.8.√1...
12-x=256-256√13+416-208√13+169+832
x=464√13-1673+12=464√13-1675
(⁴√(12 - x))⁴=(4-√ 13)⁴
12 - x= (4-√13)² (4-√13)²
12-x=(16-8√13+13) (16-8√13+13)
12-x=16.16-2.16.8√13+2.16.13-2.13.8.√1...
12-x=256-256√13+416-208√13+169+832
x=464√13-1673+12=464√13-1675
