Evaluate Using Scientific Notation (210^3)(310^5)

$(2 \cdot 10^{3}) (3 \cdot 10^{5})$

Step 1

Multiply $2$ by $3$ .

$6 (10^{3} \cdot 10^{5})$

Step 2

Multiply $10^{3}$ by $10^{5}$ by adding the exponents.

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

$6 \cdot 10^{3 + 5}$

Add $3$ and $5$ .

$6 \cdot 10^{8}$
