Evaluate Using Scientific Notation (2.410^-1)-(5.510^-2)

$(2.4 \cdot 10^{- 1}) - (5.5 \cdot 10^{- 2})$

Step 1

Multiply $- 1$ by $5.5$ .

$2.4 \cdot 10^{- 1} - 5.5 \cdot 10^{- 2}$

Step 2

Move the decimal point in $- 5.5$ to the left by $1$ place and increase the power of $10^{- 2}$ by $1$ .

$2.4 \cdot 10^{- 1} - 0.55 \cdot 10^{- 1}$

Step 3

Factor $10^{- 1}$ out of $2.4 \cdot 10^{- 1} - 0.55 \cdot 10^{- 1}$ .

$(2.4 - 0.55) \cdot 10^{- 1}$

Step 4

Subtract $0.55$ from $2.4$ .

$1.85 \cdot 10^{- 1}$
