Change the number into standard form and rewrite the statements

The thickness of human hair is in the range of $0.08 \mathrm{mm}-0.12 \mathrm{mm}$.

If standard form of the statements: The height of Mount Everest is $8848 \mathrm{m}$ is $8.848\times a^{k }\mathrm{m}$. 

Then find the value of $a+k$.

If the standard form of $0.0000456$ is $4.56\times a^k$.

Then find the value of $\mathrm{a+k}$.

If the standard form of $0.000000529$ is $5.29\times a^k$. 

Then find the value of $\mathrm{a+k}$.

if standard form of $0.0000000085$ is $8.5\times a^k$. 

Then find the value of $\mathrm{a+k}$.

The standard form $6020000000$ is $6.02\times {10}^k$. 

Then find the value of $10+k$.

Standard form of $35400000000$ is $3.54\times {10}^k$, find the value of $k$.
