    Hi! We can solve this type of problem using the trick as below:- (5^7)/(7^5)= (7-2)^7/7^5= 7^2-(2^7/7^5) =49-(128/7^5) 1 i.e. 5^7 7^5 All d best Sunil

        the sum of two numbers=144 their HCF=24 that means one no:=24x other no:=24y now, 24x+24y=144; by trial error method taking two unlike values of x and y

          the sum of two numbers=144
          their HCF=24
           
          that means one no:=24x
          other no:=24y
           
          now, 24x+24y=144;
           
          by trial error method taking two unlike values of 'x' and 'y'
          x-=1,y=5: 24(1)+24(5)=144.
          when you take smaller values of 'x', take bigger values of 'y' and vice-versa.

          ANSWER: the nos: are 24 and 120.
