Answer:

4, 8, 16,64 and 4096.

Explanation:

We are already given:
4096=2^(12)

To determine other whole numbers that can be raised to a power to obtain 4096, we apply the product rule of indices.

Product Rule of Indices:
a^(xy)=(a^x)^y

Now 12 can be factored in the following ways where one of the terms must be a perfect square:

  • 12=2 X 6
  • 12 =6 X 2
  • 12 =3 X 4
  • 12 =4 X 3
  • 12=1 X 12


2^(12)=(2^2)^6=4^6\\\\2^(12)=(2^6)^2=64^2\\\\2^(12)=(2^4)^3=16^3\\\\2^(12)=(2^3)^4=(8^2)^2=8^(2*2)=8^4\\\\2^(12)=(2^(12))^1=4096^1 $(This is the trivial case)

Therefore, the other whole numbers that can be raised tp a power to obtain 4096 are: 4, 8, 16, 64 and 4096.
