Understanding 2 to the Power of 10
What does 210 mean?
When you see the mathematical expression 2 to the power of 10 (written as 210), it means that the base number (2) is being multiplied by itself ten times. The small number at the top right is called the exponent.
$$2^{10} = \underbrace{2 \times 2 \times \dots \times 2}_{10 \text{ times}} = 1024$$Why is 1024 a Milestone in Computing?
In the decimal system (base-10), we usually group things by thousands (like a kilometer being 1,000 meters). But computers “think” in binary (base-2). Because 210 equals 1024, which is extremely close to 1,000, computer scientists adopted it as the digital equivalent of a “kilo.”
This is why file sizes and computer memory use 1024 as their multiplier:
- 1 Kilobyte (KB) = 1024 Bytes
- 1 Megabyte (MB) = 1024 Kilobytes
- 1 Gigabyte (GB) = 1024 Megabytes
Basic Rules Applied to 210
Multiplying with 210
Multiply 210 by another power of 2 by simply adding the exponents together.
$$2^{10} \times 2^2 = 2^{10+2} = 2^{12} = 4096$$Dividing with 210
Divide a larger power of 2 by 210 by subtracting the exponents.
$$\frac{2^{12}}{2^{10}} = 2^{12-10} = 2^2 = 4$$Negative Exponent (2-10)
A negative exponent turns the number into a fraction. Because 1024 is quite large, 2-10 is a very small decimal!
$$2^{-10} = \frac{1}{2^{10}} = \frac{1}{1024} \approx 0.0009765625$$
