Question

√5x+√3x+1/√5x-√3x+1=9 use the proportional form and solve​

Answer 1

Answer :-

→ √5x + √(3x+1) /√5x - √(3x+1) = 9

using C and D,

→ √5x / √(3x + 1) = 9 + 1 / 9 - 1

→ √5x / √(3x + 1) = 10 / 8

→ √5x / √(3x + 1) = 5/4

squaring both sides,

→ 5x/ (3x + 1) = 25/16

→ x/(3x + 1) = 5/16

→ 16x = 5(3x + 1)

→ 16x = 15x + 5

→ 16x - 15x = 5

→ x = 5 (Ans.)
