Question

Using properties of proportion, solve for x:(in the attachment)​

Answer 1

Answer:

x=4

Step-by-step explanation:

(x⁴ + 1): (2x²) = 17:8

Componendo and dividendo

(x⁴ + 1 + 2x²) : (x⁴ + 1 - 2x²) = 17+8: 17-8

(x² + 1)² : (x² - 1)² = 25:9

square rooting both sides

(x + 1) : (x - 1) = 5:3

Componendo and dividendo

(x + 1 + x - 1) : (x + 1 - x + 1) = (5+3) : (5-3)

2x : 2 = 8 : 2

x = 4

Hope this helps.
