Evaluate Using Scientific Notation (2.810^-5)-(1.610^-6)

$(2.8 \cdot 10^{- 5}) - (1.6 \cdot 10^{- 6})$

Step 1

Multiply $- 1$ by $1.6$ .

$2.8 \cdot 10^{- 5} - 1.6 \cdot 10^{- 6}$

Step 2

Move the decimal point in $- 1.6$ to the left by $1$ place and increase the power of $10^{- 6}$ by $1$ .

$2.8 \cdot 10^{- 5} - 0.16 \cdot 10^{- 5}$

Step 3

Factor $10^{- 5}$ out of $2.8 \cdot 10^{- 5} - 0.16 \cdot 10^{- 5}$ .

$(2.8 - 0.16) \cdot 10^{- 5}$

Step 4

Subtract $0.16$ from $2.8$ .

$2.64 \cdot 10^{- 5}$
