Answer 2

Answer:

Step-by-step explanation:

3) HCF of 85 and 153

 

85 = 5*17

153 = 3*3*17

HCF = 17 ( which is equal to 85m - 153)

so  85m-153 = 17

              85m = 17+153

             85m =  170

                  m = 170/85

                   m= 2

4)    a=x^3 * y^2

      b=x * y^4

so HCF = x * y^2
