 {2}^{(x - 4)}  \times  {2}^{ - 3}  \times  {5}^{(x - 4)}  = 1250 \\  {10}^{(x - 4)}  = 1250 \times 8 \\  \\  {10}^{(x - 4)}  =  {10}^{4}  \\  \\ on \: compairing \\  \\ x - 4 = 4 \\ x = 4+ 4 \\  \\ x = 8

x=8 this is your Answer.


pratap1ns1: I don't think that's is right, answer should be X = 8
TanujaBalodhi: yes you are right
TanujaBalodhi: can you give explanation
TanujaBalodhi: please
pratap1ns1: After 10^(x-4) = 10^4 then 10^x * 10^-4 = 10^4, 10^x = 10^4/10^-4, 10^x = 10^4 * 10^4, 10^x = 10^8, And x = 8
pratap1ns1: can't do better in comments
shashankavsthi: my mistake dude.. after compairing i wrote x-4=10 instead x-4=4
shashankavsthi: now i corrected
