Then no. of 1 address instructions is (2^6-x)*2^5 and that is given as 128. So, (64-x)*32=128 => 64-x = 4 => x=60 1 votes 1 votes Abbas commented Aug 13, 2018 reply Follow Share Ok...so can be solved like an equation: 216 = 27 * 25 + x * 210 x= 60 1 votes 1 votes Please log in or register to add a comment.
