Answer variants:

(8 \times 10^{3}) + (9 \times 10^{2}) + (7 \times 10^{1}) + (9 \times 10^{- 2}) + (4 \times 10^{- 1})

(6 \times 10^{4}) + (5 \times 10^{2}) + (4 \times 10^{0}) + (3 \times 10^{- 3}) + (2 \times 10^{- 2}) + (1 \times 10^{- 1})

(8 \times 10^{2}) + (9 \times 10^{0}) + (7 \times 1) + (9 \times 10^{- 1}) + (4 \times 10^{- 2})

(6 \times 10^{4}) + (5 \times 10^{2}) + (4 \times 10^{1}) + (3 \times 10^{- 1}) + (2 \times 10^{- 2}) + (1 \times 10^{- 3})

(6 \times 10^{3}) + (5 \times 10^{1}) + (4 \times 10^{0}) + (3 \times 10^{- 1}) + (2 \times 10^{- 2}) + (1 \times 10^{- 3})

(8 \times 10^{2}) + (9 \times 10^{1}) + (7 \times 10^{0}) + (9 \times 10^{- 1}) + (4 \times 10^{- 2})

Expand using exponents:

(i) \(6054.321\) \(=\)

(ii) \(897.14\) \(=\)
