Final answer:
To express 16² as a power with base 2, we can write it as 2^4.
Step-by-step explanation:
To express 16² as a power with base 2, we need to find the power to which 2 needs to be raised to get 16. We can start by writing 16 as a multiplication of 2 multiplied by itself:
16 = 2 × 2 × 2 × 2.
Since there are 4 2's in the multiplication, we can write 16 as 24.
