How to solve this derivative.

f(x)={ln(3x)}^2x
with steps...

Rewrite f(x) as a nested exponential-logarithm expression :

(where )

One of the properties of logarithms lets us drop the exponent as a coefficient:

Now, by the chain rule, we have

By the product rule,

By the chain rule again,

Then simplify this to

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
