Solution

The correct option is A 9000.09
Note that $9 \times 10^{- 2} = 9 \times \frac{1}{100} = 0.09 .$
Thus, the usual forms of the expressions $9 \times 10^{3}$ and $9 \times 10^{- 2}$ are given by $9000$ and $0.09$ respectively.
$∴ (9 \times 10^{3}) + (9 \times 10^{- 2}) = 9000 + 0.09 = 9000.09.$
