Question

If x+√15=4 , then x+1/x=?​

Answer 1

Answer:

24

Step-by-step explanation:

Step 1:

Collect Like Terms and calculate

x = 4 - √15

N/B: √15 ≅ 3.8

∴ x = 4 - 3.8 = 0.2

Step 2:

Since we got our x to be equal to 0.2, we will substitute the value into the second equation and simplify

0.2 + 1 / 0.2

1.2 / 0.2 ⇒ (12/10) ÷ (2/10)

             ⇒ (12/10) · (10/2)

             ⇒ (6/5) ·(5)

             ⇒ 24
