Evaluate Using Scientific Notation (2.310^4)-(6.510^3)

$(2.3 \cdot 10^{4}) - (6.5 \cdot 10^{3})$

Step 1

Multiply $- 1$ by $6.5$ .

$2.3 \cdot 10^{4} - 6.5 \cdot 10^{3}$

Step 2

Move the decimal point in $- 6.5$ to the left by $1$ place and increase the power of $10^{3}$ by $1$ .

$2.3 \cdot 10^{4} - 0.65 \cdot 10^{4}$

Step 3

Factor $10^{4}$ out of $2.3 \cdot 10^{4} - 0.65 \cdot 10^{4}$ .

$(2.3 - 0.65) \cdot 10^{4}$

Step 4

Subtract $0.65$ from $2.3$ .

$1.65 \cdot 10^{4}$
