  1. ~ Bạn tham khảo~
    x – 50^2 = 2^2 . 3 .5^4
    x-2500 = 4 . 3 . 625
    x – 2500 = 7500
    x = 7500 + 2500
    x = 10000
    Vậy x = 10000
     

  2. ~ Bạn tham khảo ~
    x-50^2=2^2*3*5^4
    => x-50 = 4*3*625
    => x-50=12*625
    => x-50=7500
    => x=7500+50
    => x=10000
    Vậy x=10000
