2 to the power of 9, written as 29, equals 512. This is calculated by multiplying the base, which is 2, by itself a total of 9 times.
To break it down:
- 2 x 2 = 4
- 4 x 2 = 8
- 8 x 2 = 16
- 16 x 2 = 32
- 32 x 2 = 64
- 64 x 2 = 128
- 128 x 2 = 256
- 256 x 2 = 512
Alternatively, we can also represent it as powers of 2:
21 = 2
22 = 4
23 = 8
24 = 16
25 = 32
26 = 64
27 = 128
28 = 256
29 = 512
This shows clearly how exponential growth works—each step raises the result by a factor of 2. So whenever you see a power of 2, it indicates how many times you are doubling a number, which leads us to the final answer of 512 for 29.
