Answer:
x = 8
Step-by-step explanation:
→ Add 16 to both sides
x = 8
Let and . By the product rule,
By the power rule, we have and , but are functions of , so we also need to apply the chain rule:
and we have
So we end up with
Replace to get everything in terms of :
We can simplify this by factoring:
9
27/9 = 3
54/9 = 6
81/9 = 9
The independent variable (x) is the domain
