Answer: There are 6046 digits will be written on expansion upto 2015th power.
Step-by-step explanation:
Since we have given that
[tex]1000^{2015}[/tex]
We have to find the number of digits ,
So,
[tex]1000^{2015}\\\\=(10^3)^{2015}\\\\=10^{6045}[/tex]
Since we know that
[tex]10^n\text{ has n+1 number of digits }[/tex]
so,
[tex]10^{6045}\text{ has 6046 number of digits }[/tex]
Hence, there are 6046 digits will be written on expansion upto 2015th power.
