[tex]2 \times 10^{19}[/tex] times more stars are there in universe compared to human eye can see
Given that, conservative estimate of the number of stars in the universe is [tex]6 \times 10^{22}[/tex]
The average human can see about 3,000 stars at night with only their eyes
To find: Number of times more stars are there in the universe, compared to the stars a human can see
Let "x" be the number of times more stars are there in the universe, compared to the stars a human can see
Then from given statement,
[tex]\text{Stars in universe} = x \times \text{ number of stars human can see}[/tex]
Substituting given values we get,
[tex]6 \times 10^{22} = x \times 3000\\\\x = \frac{6 \times 10^{22}}{3000}\\\\x = \frac{6 \times 10^{22}}{3 \times 10^3}\\\\x = 2 \times 10^{22-3}\\\\x = 2 \times 10^{19}[/tex]
Thus [tex]2 \times 10^{19}[/tex] times more stars are there in universe compared to human eye can see
