Evaluate Using Scientific Notation (1.1710^-8)(0.9*10^7)

$(1.17 \cdot 10^{- 8}) \cdot (0.9 \cdot 10^{7})$

Step 1

Multiply $1.17$ by $0.9$ .

$1.053 (10^{- 8} \cdot 10^{7})$

Step 2

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

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

$1.053 \cdot 10^{- 8 + 7}$

Add $- 8$ and $7$ .

$1.053 \cdot 10^{- 1}$
