Evaluate Using Scientific Notation (210^7)(3.410^8)

$(2 \cdot 10^{7}) (3.4 \cdot 10^{8})$

Step 1

Multiply $2$ by $3.4$ .

$6.8 (10^{7} \cdot 10^{8})$

Step 2

Multiply $10^{7}$ by $10^{8}$ by adding the exponents.

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

$6.8 \cdot 10^{7 + 8}$

Add $7$ and $8$ .

$6.8 \cdot 10^{15}$
