**Answer:**

or what values of x would this function be difficult to compute in a computer; x is approximately **zero.**

The best way to avoid the difficulty is to solve for the inverse of the expression given ,i.e solve for f(x) = 1 / √x2+ 2x+ 2−x−1**.**

**Step-by-step explanation:**

The detailed steps is as shown in the attached file.

**Answer:**

55,516 ÷ ? = 5.5516 - ? = 1,000

5,551,600 ÷ 10,000 = ? - ? = 555.16

? ÷ 10,000 = 55,516 - ? = 5.5516

55,516,000,000 ÷ 10,000 = ? - ? = 5551600

**Step-by-step explanation:**

Hey there!

From the given figure;

An exterior angle is 127°.

**To ****find****:**** **value of"X"

Now;

x+127° = 180°. [Being linear pair]

or, X = 180° - 127°

or, X = 53°

**Therefore****,**** ****the ****value**** ****of ****"****X"**** ****is ****5****3****°****.**
