Question

I don't know what to do with the 3 over the square root once I get the problem simplified...I've been skimming in the book but haven't found it yet... Here is the problem... http://einstein.math.fsu.edu:9080/testbanks/wiley/math/2233PT/cch/images/qu.9.3.question.gif

Answer 1

The 3 over the root symbol means it is a cube root.

The limit as x->5 of [3(1-2x)]^1/3
is [-27]^1/3

=-3
