x+y+z=9

Step-by-step explanation:

 {2}^{x} . {5}^{y} . {7}^{z}  = 98 \times  {10}^{3}  \\ {2}^{x} . {5}^{y} . {7}^{z}  =2 \times 7 \times 7 \times  {(2 \times 5)}^{3} \\ {2}^{x} . {5}^{y} . {7}^{z}  = {2}^{4}  \times  {5}^{3}  \times  {7}^{2}  \\ comparing \:bases \: and \: powers \\ we \: get \\ x = 4 \\ y = 3 \\ z = 2 \\ x + y + z = 9
