Find the first 3 terms in binomianl series to calculate approximate value of:

The binomial series looks like this:

We have: . . . . where:

The first three terms are: .

. .

Therefore: .

~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~

This is a very good approximation!

The actual value is: .

Our answer gives us: .
