Evaluate Using Scientific Notation (810^-18)(3.2510^5)

$(8 \cdot 10^{- 18}) (3.25 \cdot 10^{5})$

Step 1

Multiply $8$ by $3.25$ .

$26 (10^{- 18} \cdot 10^{5})$

Step 2

Multiply $10^{- 18}$ by $10^{5}$ by adding the exponents.

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

$26 \cdot 10^{- 18 + 5}$

Add $- 18$ and $5$ .

$26 \cdot 10^{- 13}$

Step 3

Move the decimal point in $26$ to the left by $1$ place and increase the power of $10^{- 13}$ by $1$ .

$2.6 \cdot 10^{- 12}$
