What is the value of n in the equation below?

12

Step-by-step explanation:

We can use the property of exponents    over here.

Let's use this property to write:

This is equal to a^9, hence, n - 3 = 9. Let's solve for n:

n = 12

option C

12

Step-by-step explanation:

Given in the question an expression

To solve for n we will use rules of exponent

cross multiply

apply product rule

Apply logarithm on both sides of equation

apply power rule of logarithm

nln(a) = 12ln(a)

ln(a) will cancel out on each side so we are left with

n= 12

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
