Evaluate Using Scientific Notation (2.310^-3)(310^8)

$(2.3 \cdot 10^{- 3}) (3 \cdot 10^{8})$

Group coefficients together and exponents together to multiply numbers in scientific notation.

$(2.3 \cdot 3) (10^{- 3} \cdot 10^{8})$

Multiply $2.3$ by $3$ .

$6.9 (10^{- 3} \cdot 10^{8})$

Multiply $10^{- 3}$ by $10^{8}$ by adding the exponents.

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

$6.9 \cdot 10^{- 3 + 8}$

Add $- 3$ and $8$ .

$6.9 \cdot 10^{5}$
