Randall,
I think you are confusing two different concepts.
10^2 = 100, not 2^10 = 100.
What you want is something like this:
Step 1) 10^x = 100
Step 2) log 10^x = log 100
Step 3) x log 10 = log 100
Step 4) x = log 100 / log 10
In short, you need to use logarithms and you'll get a formula where x
= log y / log z.
If you were trying to solve x^10 = 100, then you could do what you
suggest and just raise both side to the (1/10)th power. But that
number will not be 2 -- it's about 1.58.
I can't remember how to use power function "^" to find the nth root
of a number. To find the 2ndth root of a number we can use the
"sqrt()" function. But to find the nth root????
For instance, lets say I want to convert a number to scientific
notation (the 10th root of that number)... I used to know how to use
the power function to do this. Anyone remember how to do it?
I tried to get the 10th root (scientific notation) of 100 (which
should = 2) by: 100^(1/10) ... but that isn't it.
Any ideas? I feel brain dead.
Randall
