Evaluate Using Scientific Notation (1.610^-7)(2.9*10^-8)

$(1.6 \cdot 10^{- 7}) \cdot (2.9 \cdot 10^{- 8})$

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

$(1.6 \cdot 2.9) (10^{- 7} \cdot 10^{- 8})$

Multiply $1.6$ by $2.9$ .

$4.64 (10^{- 7} \cdot 10^{- 8})$

Multiply $10^{- 7}$ by $10^{- 8}$ by adding the exponents.

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

$4.64 \cdot 10^{- 7 - 8}$

Subtract $8$ from $- 7$ .

$4.64 \cdot 10^{- 15}$
