Easy significant figures questions?

Question

(44.4)^(-1), isnt it is 1/(44.4) ?

if so, the significant is 1 though? or the answer is 0?

if not, it is 3 significant figure or 0.023? or 0.0225?

Answer 1

The -1 is not a significant figure as it denotes raising to a power, which  is an operation, not an operand. The same applies to the 1 in 1/44.4 because it denotes the operation of inversion. 0.0225 is the answer to 3 significant figures

Answer 2

I think the ^(-1) part is not a measurable value, but a logic one, so it does not count for the significant figures, so theright answer would be 0.0225
