Solve with due regards to significant figures: ( 6.0 × 10 − 4 − 4.5 × 10 − 6 ) . Give the answer in units of 10 − 4 .

( 6.0 × 10 − 4 ) − ( 0.045 × 10 − 4 ) = 5.955 × 10 − 4 The least accurate term is known to 0.1 × 10 − 4 , so round to one decimal place in these units: 6.0 × 10 − 4

Solve with due regards to significant figures: $(6.0 \times 10^{- 4} - 4.5 \times 10^{- 6})$ . Give the answer in units of $10^{- 4}$ .

Answer:

6.00

Solution:

$(6.0 \times 10^{- 4}) - (0.045 \times 10^{- 4})$

$= 5.955 \times 10^{- 4}$

The least accurate term is known to $0.1 \times 10^{- 4}$ , so round to one decimal place in these units: $6.0 \times 10^{- 4}$
