Evaluate Using Scientific Notation 1.410^9-8.610^8

$1.4 \cdot 10^{9} - 8.6 \cdot 10^{8}$

Step 1

Move the decimal point in $- 8.6$ to the left by $1$ place and increase the power of $10^{8}$ by $1$ .

$1.4 \cdot 10^{9} - 0.86 \cdot 10^{9}$

Step 2

Factor $10^{9}$ out of $1.4 \cdot 10^{9} - 0.86 \cdot 10^{9}$ .

$(1.4 - 0.86) \cdot 10^{9}$

Step 3

Subtract $0.86$ from $1.4$ .

$0.54 \cdot 10^{9}$

Step 4

Move the decimal point in $0.54$ to the right by $1$ place and decrease the power of $10^{9}$ by $1$ .

$5.4 \cdot 10^{8}$
