Math Problem Statement

What is the answer?

What is the decimal equivalent of the binary number (10110)_2?

Solution

The image shows a binary number (10110)2(10110)_2 that needs to be converted into its decimal (base 10) equivalent.

To convert a binary number to a decimal number, we multiply each bit by 2 raised to the power of its position, starting from 0 on the right:

(10110)2=124+023+122+121+020(10110)_2 = 1 \cdot 2^4 + 0 \cdot 2^3 + 1 \cdot 2^2 + 1 \cdot 2^1 + 0 \cdot 2^0

Calculating each term:

124=161 \cdot 2^4 = 16 023=00 \cdot 2^3 = 0 122=41 \cdot 2^2 = 4 121=21 \cdot 2^1 = 2 020=00 \cdot 2^0 = 0

Adding them together:

16+0+4+2+0=2216 + 0 + 4 + 2 + 0 = 22

Therefore, (10110)2=2210(10110)_2 = 22_{10}.
