Question

If (x - y) is power of 3 and is equal to 27. (x + y) is power of 3 and is equal to 243, then x is equal to:​

Answer 1

Answer:

x=4

As 3^3=27

And 3^5=243

Therefore, (x-y)=(4-1) to get the desired outcome of 27.                                                        

                  (x+y)=(4+1) to get the desired outcome of 243.
