Question

If 84 is equal to 64 the what is the possible value of x and y

Answer 1

Answer:

Step-by-step explanation:

84 is a base of x and 64 is the base of y

So,

8(x^1)+4(x^0) = 6(y^1) + 4(y^0)

8x - 6y = 4 - 4

8x - 6y = 0

Some of the possible integral solutions are :

(3,4) which cannot bocoz 84 is not in base of 4

So possible answer is (6,8)
