What is the function opposite of LOG

What is the function (and where can I find it) opposite of LOG, e.g.
Inverse Log(Log10) = 10)?

No function needed. The inverse log is simply the base raised
to the power of the logarithm. In the case of LOG(), the base
is 10. So 10^LOG(x) = x.

Likewise, e^LN(X) = X. But "e" is not a reserved symbol in
Excel. Hence the need for EXP().

depends upton
log(10,10) is 1
reverse is power functin
10 to the power 1(a0^1) is10

simialrly log(10,2) is 3.321928
so 2^3.321928 is 10


LN is the log to the base e(exponetial)
LN(86) is 4.454347

exp is the worksheet function for exponential
exp(4.454347) is 86

Yes, __do__ read the Help text. I wrote "LOG(x)" with no
"base" parameter. The default base is 10. So while it is
true that you may specify other bases, what I wrote was
not incorrect for base 10.

I interpreted the OP's question to be about log to base 10. I
mentioned LN() only to explain why the OP might have found
EXP(), which I thought might have set his expectation for
something comparable for LOG().
