Evaluate Using Scientific Notation (310^2)(210^5)

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

Step 1

Multiply $3$ by $2$ .

$6 (10^{2} \cdot 10^{5})$

Step 2

Multiply $10^{2}$ by $10^{5}$ by adding the exponents.

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

$6 \cdot 10^{2 + 5}$

Add $2$ and $5$ .

$6 \cdot 10^{7}$
