I am new to number theory and struggling to understand how to take a binary representation and use exponentiation to determine the value. For example, if the binary exponentiation is represented as follows, how do I work out the value by hand? The hint provided by in the question is to consider what $$2^{2}$$, or $$2^{3}$$ looks like.
$$x =(2^{12} \times 2^{20})−2^0$$
edit: I believe I've solved it as follows. Thanks for your help. Proposed Solution
