How can we find the antilogarithm of 9.485?

On my calculator which is a old Sharp:

2nd
log
9.485
= 3054921113

in effect you are finding 10^9.485

so you could use the y^x key,
enter:
10
y^x
9.485
=
how about that, the same answer.

(Calculators would function quite well without the y^x key, as a matter of fact internally the calculator actually works in logs . "They" gave us that key only as a convenience)
