Is this the whole problem because I don’t see a “g”
Anywhere I’m the problem
No, it is an imaginary number.
Can't take the square root of a negative number without creating a method termed an imaginary number, which is the square root of -1 which they have used " i " to signify.
Then square root of -11.2 would be written Sqrt(11.2)i. The Sqrt(11.2) = 3.3466
so the answer is 3.3466i
We have to find the expansion of 
We will use binomial expansion to expand the given expression, which states that the expression
is expanded as :

Now expanding
we get,


So, the variables are
