Question

What is the resulting value for the Hubble constant?Write your answer in scientific notation

Answer 1

$\bf{Given : Hubble\;Constant(H_0) = 73(\frac{km}{s \times Mpc})}$

$\bf{Given : Conversion\;Factor = (\frac{1Mpc}{3.086 \times 10^1^9\;km})}$

$\bf{\implies Resulting\;Hubble\;Constant = 73(\frac{km}{s \times Mpc})(\frac{1Mpc}{3.086 \times 10^1^9\;km})}$

$\bf{\implies Resulting\;Hubble\;Constant = 73(\frac{1}{s \times 3.086 \times 10^1^9})}$

$\bf{\implies Resulting\;Hubble\;Constant = (\frac{23.65}{s \times 10^1^9})}$

$\bf{\implies Resulting\;Hubble\;Constant = 2.365 \times 10^-^1^8(1/s)$
