You can put this solution on YOUR website! I think what you are expressing is x equals the log to the base 11 of 1331.
.
This can be rewritten in exponential form as:
.
.
Now you can take the log to the base 10 of both sides to get:
.
.
By the rules of logs the exponent x comes out as the multiplier of log 11 to give
.
.
Now you can use your calculator in log to the base 10 mode to get that log 11 = 1.041392685.
Similarly you can use your calculator in log to the base 10 mode to find that log 1331 =
3.124178055.
.
Substitute these two values into our equation to get:
.
.
Now solve for x by dividing both sides by 1.041392685 to get:
.
.
So the answer to this problem is x = 3.
.
Because the values are relatively small, when you got to the exponential form of:
.
.
You could have just plugged values in for x until you got to but that
is just a "test taking" trick. The rigorous way to do it is using the procedures above.
.
Hope this helps you to see your way through this problem. It has some good practice
with working with logs.
