(10^4)  74 = ? (10^4)  10*7.4 = ? 10*[(10^3)  7.4] = ? 10*[10^3  7.4] = 992.6*10 = 9926 = 9*2+2+6 = 26 Note that 10^4 will yield two nines a six and a two. so solving for 10^50 and 74 will give 48 nines a six and a two: 10*[10^49  7.4] = 9*48+2+6 = 440

You get 48 nines,but the LAST numbers are 2 and 6, we take them in and add them. 10(10^497.4)=99999999999999999999999999999999999999999999999926
