Question

Absolute value of sqrt(5) - 2.2

Answer 1

0.03607

Explanation:

Absolute value is the distance of a number from zero. Since distance is always positive, the absolute value is the same number but positive.

Please note, for this problem I have rounded to 5 decimal points because the answer is irrational.

Subtracting

There are 2 different ways to approach this problem. You can either estimate the square root of 5 or plug this question straight into a calculator.

First, we can estimate
`√(5)` and round to 5 decimal places.

• 
  `√(5)` ≈ 2.23607

Then, take this value and subtract.

• 2.23607 - 2.2 = 0.03607

Absolute Value

Now that we have solved the subtraction problem we have to find the absolute value. As stated above, the easiest way to find absolute value is to simply make the number positive. Since the answer is already positive, this is the final answer.

• |0.03607| = 0.03607
