Evaluate Using Scientific Notation (210^5)(4.4*10^7)

$(2 \cdot 10^{5}) \cdot (4.4 \cdot 10^{7})$

Step 1

Multiply $2$ by $4.4$ .

$8.8 (10^{5} \cdot 10^{7})$

Step 2

Multiply $10^{5}$ by $10^{7}$ by adding the exponents.

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$8.8 \cdot 10^{5 + 7}$

Add $5$ and $7$ .

$8.8 \cdot 10^{12}$
