2^n - 3 = 83
<span>2^n = 86 </span>
<span>ln(2^n) = ln(86) </span>
<span>n*ln(2) = ln(86) </span>
<span>n= ln(86)/[ln(2)] (which is the same as "log base 2 of 86") </span>
<span>n= 6.426264755</span>
1 gallon / 200 ft^2 = x gallons / 885ft^2
cross multiply (200 • x, 1 • 885)
200x = 885
x = 4.425 gallons
Answer 1.37, 1 1/4, 1.16, 1 1/10
Step-by-step explanation:
1.37
1 1/4 (1.25)
1.16
1 1/10 (1.1)
There are 10 digits possible for each of the 4 places .
So the number of digits possible is 10^4 = 10,000
