Answer 2

Step-by-step explanation:

${2}^{50} \times {5}^{48} = > {2}^{48} \times {2}^{2} \times {5}^{48} = >$

${10}^{48} \times 4$

So the last digit or unit digit in

${2}^{50} \times {5}^{48}$

is 0. Hence when we subtract 9 from it we get 3 followed by 46 9's and 1. Hence the unit digit in the above mentioned number is 1.
