There are many benefits to timing your practice, including:

When I wrote (1), I meant the first part of the problem. If you see the expression, you will see that my choice was #2 (1.6 * 10 ^ 21).

KPadma,
It is asking for the expression which can be formatted in the form of n^4, where n is a integer. You will see why expression#2 (1.6 * 10 ^ 21) can be formatted into that form.

VT,
If (e) is the right answer then 1.6 * 10 ^24 can be expressed as n^4. Which is wrong even if ETS says it. Because, if you take
1.6 * 10 ^24
= 16 * 10^23
= 2^4 * 10 ^ 20 * 10^3
= 2^4 * (10^5)^4 * 1000
= (2*10^5)^4 * 1000

which clearly is not in the form n^4. If (E) is the answer, please recheck the question. Thanks
