Let f(x) = x^(1/3). The equation of the tangent line to f(x) at x = 8 can be written in the form y = mx+b where m is: and where b is:(adsbygoogle = window.adsbygoogle || []).push({});

Using this, we find our approximation for 8.1^(1.3) is:

I found the slope to be 1/12

I found b to be 1.3333333333333333333

I still can't get the answer for the approximation for 8.1^(1/3).

I plugged it correctly in the mx+b equation but it won't work.

Is there another way to do this? Please help.
