what is the 7 power of 73
Of course reading of calculator makes everything easy, but don't get anything out of it.
But I think the purpose was to use Logarithms function, before calculators had to calculate it from the tables
log -1 ( 7 (log 73)) = 1.105* 1013 / This relation is that Logs and exponents are inverse of each other. / it is smart use of calculator, that there is
/ no need to calculate each component
73 ^ 7 = 1.105* 1013
That is exactly the way I entered into calculator.
Notice that log-1 appears in calculator as 10X.
