You can use Newton's method. Alternatively, write and approximate by using the Taylor series which is valid for . You would get by this method.
Hello, mzkmikey!
I believe they want us to use differentials.Approximate using calculus.
We have the function: .
The differential is: .
Let
We know that: .
. . where is actual difference between and
And we know:. . .[1]
. . where is an approximation of
We have: .
Therefore: .
