Evaluate Using Scientific Notation (3.210^5)(1.410^-2)

$(3.2 \cdot 10^{5}) (1.4 \cdot 10^{- 2})$

Step 1

Multiply $3.2$ by $1.4$ .

$4.48 (10^{5} \cdot 10^{- 2})$

Step 2

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

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

$4.48 \cdot 10^{5 - 2}$

Subtract $2$ from $5$ .

$4.48 \cdot 10^{3}$
