(2^100) - (2^99)
im supposed to be doing pretty advance stuff but this just stumps me
can someone show me how this is done? the answer is to be in the form 2^n
ok not too hard. the answer is 2^1. When your adding indices you add the top and when your subtracting them you subtract the indices. Try check this website out:
