Use a linear approximation (or differentials) to estimate the given number.. (1.999)^4

For this specific problem:

f(x) = x4, a= 2 and x= 1.999 

Going with this, 1.9994 = 24 + 4 * (23) * (- 0.001) = 15.968 

I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

i think da answer is

d.square root of 3

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.
