`2^1995+2^1995+2^1995+2^1995+2^1995+2^1995+2^1995+2^1995=2^x`

We can simplify this problem as:

`8(2^1995)=2^x`

We know that 8=2^3 theregore:

`(2^3)(2^1995)=2^x`

Following the rule of exponenets that state the following:

`x^mx^n=x^(m+n)`

Therefore:

`(2^3)(2^1995)=2^(3+1995)=2^1998=2^x`

Therefore, x=1998, so the answer is c.
