Answer 2

Answer:

$Value \:of \:x = 100$

Step-by-step explanation:

$\frac{1}{8!}+\frac{1}{9!}=\frac{x}{10!}$

$\implies \frac{1}{8!}+\frac{1}{9\times 8!}=\frac{x}{10\times 9\times 8!}$

/* Multiply both sides by 8! , we get

$\implies 1+\frac{1}{9}=\frac{x}{90}$

$\implies \frac{9+1}{9}=\frac{x}{90}$

$\implies \frac{10}{9}=\frac{x}{90}$

$\implies \frac{10\times 90}{9}=x$

$\implies 100=x$

Therefore,

$Value \:of \:x = 100$
