no 46 dong bantu yuuu

⁴√a + ⁴√9 = 1/(2 - √3)

a^¹/₄ + 9^¹/₄ = 1 x (2 + √3)/(2 - √3)(2 + √3)

a^¹/₄ + 9^¹/₄ = (2 + √3) / (4 - 3)

a^¹/₄ + (3²)^¹/₄ = 2 + √3

a^¹/₄ + 3^¹/₂ = 2 + √3

a^¹/₄ + √3 = 2 + √3

a^¹/₄ = 2

⁴√a = 2 ===> a = 16

semoga jelas dan membantu ya

1/(2 - √3) = (2 + √3) / (2² - √3²)
1/(2 - √3) = (2 + √3) / (4 - 3)
1/(2 - √3) = 2 + √3

⁴√a + ⁴√9 = 2 + √3
⁴√a + ⁴√9 = ⁴√2⁴ + ⁴√(√3)⁴)

a = 2⁴
a = 16
