(a) Write
as a single power if 2.
​

There are two ways to go about this problem.

The first way, the generic way, is to know that,

.

So,

.

The second way is to realise that both numerator and denominator are equal and when diving two equal numbers you obtain 1. (except when diving zeros) aka,

And 1 equals to any number raised to the power of zero,

So we just have to say that the 1 we got is rewritten as some base to the power of zero.

Since our base needs to be 2, we just simply say,

.

Et Viola.
