<h3><u>Write 6^8 • 6^7 as a single power:</u></h3>

<em><u>Solution:</u></em>
Given that,
We have to write 6^8 • 6^7 as a single power
Given is:

<em><u>Use the following law of exponent</u></em>

When, the base is same, powers gets added
Therefore,

Thus the given is written as a single power
Givens
Petri Dish A sees a double ever 10 minutes
Petri Dish B sees a double ever 6 minutes
Consequences
A doubles 60 / 10 = 6 times.
B doubles 60 / 6 = 10 times.
Solution
If you work best with numbers then suppose there are 100 bacteria in both dishes at the beginning
A = 100 * 2^6
B = 100 * 2^10
A will have 100 * 64 = 6400 bacteria growing inside A
B will have 100 * 1024 = 102400 bacteria growing inside B
B/A = 102400 / 6400 = 16
There are 16 times as many in B than in A. <<<< Answer
Y = -2x + 6
I think this is it
