You could get your calculator and find  which is
 and then mutiply that by  to get
. However that won't get you any closer
to finding !

That's because calculators as a rule can only work 
directly with numbers less than , "1 google".

You can't get  on a calculator directly because 
that number is bigger than googol. Most calculators made today 
can do anything but give an overflow error message for a google 
and anything larger.  

However you can get larger numbers indirectly on your calculator.

On my calculator I find that I can get  
directly as 

However when I try to get  I get an overflow
error message.  

We can break  down this way:

 both of which can be 
found on the calculator:

  


Then we can multiply those decimal parts,  

then add the exponents of ten and get 

So therefore



However, that's not in scientific notation because 
is not less than 10, so we write it in scientific notation as
, then substituting we have



or adding the exponents of ten:



Notice that we could have broken  down in a number
of other ways, for example:



so
.

And so we have, as above:



There is a slight difference between the two.  I would guess
that that latter is closer to the true value, but we could
safely round either answer to this:
