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 
8-3*2=10
5*6-5=25
5
10*25*5=1250
Answer:
there are 8 million different phone numbers whose phone numbers whose digits aren't 0 or 1
X = -6 hope that helps :)
