Evaluate Using Scientific Notation (4.610^4)-(3.210^3)

$(4.6 \cdot 10^{4}) - (3.2 \cdot 10^{3})$

Step 1

Multiply $- 1$ by $3.2$ .

$4.6 \cdot 10^{4} - 3.2 \cdot 10^{3}$

Step 2

Move the decimal point in $- 3.2$ to the left by $1$ place and increase the power of $10^{3}$ by $1$ .

$4.6 \cdot 10^{4} - 0.32 \cdot 10^{4}$

Step 3

Factor $10^{4}$ out of $4.6 \cdot 10^{4} - 0.32 \cdot 10^{4}$ .

$(4.6 - 0.32) \cdot 10^{4}$

Step 4

Subtract $0.32$ from $4.6$ .

$4.28 \cdot 10^{4}$
