Tolong bantu pr mtk dong Sebisa kalian aja dehh Pakai cara ya No10-15 Makasih

10. 3√12 x 2√75 = 3√4 x 3 x 2√25 x 3 = 3.2√3 x 2.5√3 = 6√3.10√3 = 60.3 = 180

11. ³√9 x ³√81 = ³√9 x 81 = ³√3².3⁴ = ³√3^6 = 3² = 9

12. 81^1/4 - 125^1/3 + 4^3/2 = (3⁴)^1/4 - (5³)^1/3 + (2²)^3/2 = 3 - 5 + 2³ = -2 + 8 = 6

13. (√5 + √2)² = 5 + 2√10 + 2 = 7 + 2√10

14. 9/√3 = 9/√3 x (√3/√3) = 9√3/3 = 3√3

15. 10/(2 - √2) = 10/(2 - √2) x ((2 + √2)/(2 +√2)) = 10(2 + √2)/(2² - √2²) = (20 + 10√2) /(4 - 2) = (20 + 10√2)/2 = 10 + 5√2 = 5(2 + √2)
Semoga membantu, kalau ada yang belum jelas, tanyakan di komentar.
