Evaluate Using Scientific Notation (6.510^8)(1.4*10^-5)

$(6.5 \cdot 10^{8}) \cdot (1.4 \cdot 10^{- 5})$

Step 1

Multiply $6.5$ by $1.4$ .

$9.1 (10^{8} \cdot 10^{- 5})$

Step 2

Multiply $10^{8}$ by $10^{- 5}$ by adding the exponents.

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

$9.1 \cdot 10^{8 - 5}$

Subtract $5$ from $8$ .

$9.1 \cdot 10^{3}$
