The closest estimate is the exact value.39*2 = (40 - 1)*2 = 80 - 2 = 78
Then 39*22 = 39*2*11 = 78*11 = 858
[Multiplication by 11 give the digits 7, 7+8 and 8 - with the carry overs applied to the answer.]

How do you estimate the derivative of a function given a numericallyValues of x and g(x) are given in the table. For what value of x is g'(x) closest to 3?
You can estimate the derivative by looking at adjacent rows of the table, and calculate (difference of y-coordinates) divided by (difference of x-coordinates).
