Step 1
we have to find the eighth term of the arithmetic sequence whose first term is 4 and whose common difference is -7.
Step 2
Let the eighth term is denoted by a8
here
a1= first term =4
d=7
now as we know that nth term is given as
an=a1+(n1)d
where a1 is the first term an d is the common difference.
a8=4+(81)(7)
a8=4+7(7)
a8=449
a8=45

Solving equations with logarithms
I'm having trouble with solving equations that has logarithms in them. For example:
x log ( x ) = 100 x
How can I solve this? I have reed about how to do it but when I try to do the same with this example I just got stuck. The only thing I can think of doing is to draw the lines and see where they cross but I only get one answer x = 10 but there should be two and I will need to show how I came up with the answer by showing calculations. Please help.

How do I evaluate this logarithm expression?
I think the answer for this is 0.01, but I'm not sure. Could someone explain the steps in solving the following for ( x / y ):
10 log 10 ( x / y ) = 20
I've tried putting 20 10 log 10 in Wolfram Alpha, but the answer doesn't look like what I was expecting.
