: I really need help !
5) Logarithms:
a) Using a calculator, find log 10000 where log means log to the base of 10.
Answer:
b) Most calculators have 2 different logs on them: log, which is based 10, and ln, which is based e. In computer science, digital computers are based on the binary numbering system which means that there are only 2 numbers available to the computer, 0 and 1. When a computer scientist needs a logarithm, he/she needs a log to base 2 which is not on any calculator. To find the log of a number to any base, we can use a conversion formula as shown here:
Using this formula, find .

Question 35103: i really need help on these ones they got me really confused i would appreciate it if i could get some help answering these thank you
find the sum of the arithmetic sequence having the data given.
a1 = 5, an = 3, n = 20
a1 = 7, d = - 3, n = 20
a1 = 81, an = - 13, n = 20
a1 = 5, d = 7, n = 120
an = 5, d = -2, n = 12
In exercises 6-7, find the first term of the arithmetic sequence having the data given.
an = 48, Sn = 546, n = 26
Sn = 781, d = 3, n = 22
