That is what the calc on the home page says ;)
You start by putting some more brackets in the expression so there can be no doubt what you intend.
The calculator on the home page says (1.0178)^48 = 2.3323699307034225
so you can just substitute this value in your expression.
Evaluate that power this way:
1.0178
x^y button
48
=
$${\frac{{\mathtt{2\,289}}{\mathtt{\,\times\,}}{\mathtt{0.017\: \!8}}}{{\mathtt{1}}}}{\mathtt{\,-\,}}{\left({\mathtt{1}}{\mathtt{\,\small\textbf+\,}}{\mathtt{0.017\: \!8}}\right)}^{-{\mathtt{48}}} = {\mathtt{40.315\: \!451\: \!546\: \!833\: \!992\: \!7}}$$
