Question

how many stars are there in each galaxy

Answer 1

According to some scientists,
There are
${10}^{11} galaxies$
and each galaxy has approximately
${10}^{11} stars$
So total stars in whole universe =
${10}^{22}$
in each galaxy
${10}^{11}$
That's what I know

Thanks.

»we all know that there are 100 billion galaxies in the entire universe

${10}^{11}$

» There are 1 billion trillion stars in the entire universe

${10}^{22}$

Now let's calculate how many stars are there in 1 galaxy

let X denote the number of stars in 1 galaxy

$x \times {10}^{11} = {10}^{22} \\ \\ x = \frac{ {10}^{22} }{ {10}^{11} } \\ \\ x = {10}^{11}$

This means there are 100,000 million stars or 100 billion stars in each galaxy

Hence ,

$\boxed{ \mathfrak{100,000 \: Million \: stars \: are \: there \: in \: each \: galaxy}}$
