Evaluate Using Scientific Notation (2.510^-9)(1.510^3)

$(2.5 \cdot 10^{- 9}) (1.5 \cdot 10^{3})$

Step 1

Multiply $2.5$ by $1.5$ .

$3.75 (10^{- 9} \cdot 10^{3})$

Step 2

Multiply $10^{- 9}$ by $10^{3}$ by adding the exponents.

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

$3.75 \cdot 10^{- 9 + 3}$

Add $- 9$ and $3$ .

$3.75 \cdot 10^{- 6}$
