Do you mean \[log(10x) = 2?\]

Or do you mean \[log_{10}(x) = 2\]

Recall that\[log_b(a) = k \iff b^k = a\]

...?
anonymous

What is b, what is a, what is k in your example?
anonymous
  • anonymous
It doesn't say

Just look at it.

Look at what I wrote on the left side. That is just like what you have except instead of b, a, and k you have other values.
anonymous
  • anonymous
So what is your b, a, and k?

All the question says is log 10 (x)=2 then some of the answers are 100 and -20 they don't give any more information

Look at what you wrote: \[log_{10}(x) = 2\] Look at what I wrote: \[log_b(a) = k\] Now, in your example what is b, what is a, and what is k?
anonymous
  • anonymous
b is 10 and k is 2 there is no a it just says x :P
anonymous
  • anonymous
a is x.

So now, by the definition of the log function: \[log_b(a) = k \iff b^k = a\] What that means is that both sides of those arrows mean the same thing, you have the left side, but it means the same thing as the right side. So you can rewrite the right side using your a, b, and k and I think you'll have a nice solution to your problem.
