To solve this divide the integrals into o to 1 ,1 1to 2 ..... upto [x]-1 to [x]

 

so you get integrations of 2^(x-0) from 0 to 1 +2^(x-1) from 1 to 2 .... upto 2^(x-[x]+1) from [x-1]to [x]

 

each integral evaluates to 1/ln2 so we have [x] terms in our integral sum expression ..

 

therefore you get  ans=[x]/ln2
