-3 is less than 0, so you are going to use 
.
Plug in values:
Answer:
○ x³\⁷
Step-by-step explanation:
Since you are multiplying ⁷√x three times, you write it like this first, ⁷√x³, then according to one of the Six Exponential Rules, ⁿ√aᵐ = aᵐ\ⁿ, ⁷√x³ gets rewritten as x³\⁷.

**In one of my You-Tube videos, it talks about all six exponential rules. The video is titled "Six Exponential Rules". Go check it out and get as much assistance as you can from the tutorial.
We will use <span>y-y1=m(x-x1), where m= f '(x)= 4x^3e^-x - x^4e^-x, f ' (1) =3e^-1
</span>f (1) =4e^-1
so the equation of tangent line tothe curve at the point <span>(1,1/e) is
y= </span>3e^-1(x-1) + 4e^-1, or y= 3e^-1(x)) + e^-1,
