If $$m$$ and $$n$$ are natural number such that $$2^m - 2^n = 960$$, what is the value of $$m$$?
Expression : $$2^m - 2^n = 960$$ -------------(i)
=> $$2^m>960$$
=> $$m\geq10$$
If, $$m=10$$
Substituting in equation (i), we get : $$1024-2^n=960$$
=> $$2^n=64=2^6$$
=> $$n=6$$
Since, both are natural numbers, => $$m=10$$
=> Ans - (A)
