write 01010010 as a decimal.

Explanation:

Step1: Identify binary - decimal conversion formula

For a binary number (a_{n}2^{n}+a_{n - 1}2^{n - 1}+\cdots+a_{1}2^{1}+a_{0}2^{0}), where (a_{i}) is either 0 or 1.

Step2: Analyze each bit's value

The binary number 01010010 can be written as (0\times2^{7}+1\times2^{6}+0\times2^{5}+1\times2^{4}+0\times2^{3}+0\times2^{2}+1\times2^{1}+0\times2^{0}).

Step3: Calculate each term

(0\times2^{7}=0), (1\times2^{6}=64), (0\times2^{5}=0), (1\times2^{4}=16), (0\times2^{3}=0), (0\times2^{2}=0), (1\times2^{1}=2), (0\times2^{0}=0).

Step4: Sum up the terms

(0 + 64+0 + 16+0 + 0+2 + 0=82).

Answer:

82
