#1**0 **

Since we know that f(4) = 1, we can plug that information into the second equation and get:

f(2*4) = 3f(4)

f(8) = 3*1

f(8) = 3

f(2*8) = 3f(8)

f(16) = 3*3

f(16) = 9

f(2*16) = 3f(16)

f(32) = 3*9

f(32) = 27

f(2*32) = 3f(32)

f(64) = 3*27

**f(64) = 81**

Hope this helped. Let me know if I did anything wrong!
