We begin with 1,000 fish in a lake.
Each year the population declines to 15%
Then they put back 500 fish in the lake.
The equation: (1000 * .85) +500
You can factor -80 as

So, we have

The square root of a product is the product of the square roots:

Since
and
, we have

Divide 108 and 72 by twelve and you get 9 and 6 which all you have to do it multiply together
Answer:

Step-by-step explanation:
First, add two to both sides to get
There are two ways to solve this from here
- Think about what power you would have to raise 9 to to get to 27.
= 3 and
. So, multiplying the powers (because it is a power to a power) you get
. This means that
or x =
. - Take the log of both sides.
This gives us
