Yes, it's the same two hexadecimal values:

0x00000065 = 5*(16^0) + 6*(16^1) + 0*(16^2) + ... + 0*(16^7) = 5*(16^0) + 6*(16^1) = 0x65

(Note: the symbol '^' denotes the power operator)

Registers are 32 bits long so you can't have 0x65 in one, only 0x00000065.

But of course, these are equal numbers.
