Answer
$6.28698 \times 10^{38}$
Work Step by Step
$\frac{(73.1)(1.6341 \times 10^{28})}{0.0000000019}$
First we need to put everything into scientific notation. So we will end up with this:
$\frac{(7.31 \times 10^1)(1.6341 \times 10^{28})}{(1.9 \times 10^{-9})}$
Next we multiply the numerator. In scientific notation we multiply the first number together then add the exponents of 10. Giving us:
$\frac{(11.94527 \times 10^{29})}{(1.9 \times 10^{-9})}$
$\frac{(1.194527 \times 10^{30})}{(1.9 \times 10^{-9})}$
Then we divide the numerator and denominator. And similar to multiplying we divide the first numbers then subtract the exponents of 10: (30 - (-9) = 39)
$0.628698 \times 10^{39}$
$6.28698 \times 10^{38}$
