The correct answer is (a) 17.<\/p>\n
To convert a binary number to decimal, you multiply each digit by the power of 2 corresponding to its position, starting from the right. The position of the rightmost digit is 2^0, the position of the next digit to the left is 2^1, and so on.<\/p>\n
In the binary number 10101, the rightmost digit is 1, so we multiply it by 2^0. The next digit to the left is 0, so we multiply it by 2^1. The next digit to the left is 1, so we multiply it by 2^2. The next digit to the left is 0, so we multiply it by 2^3. And the last digit to the left is 1, so we multiply it by 2^4.<\/p>\n
1 * 2^0 = 1
\n0 * 2^1 = 0
\n1 * 2^2 = 4
\n0 * 2^3 = 0
\n1 * 2^4 = 16<\/p>\n
Adding up the products of each digit and its corresponding power of 2, we get 1 + 0 + 4 + 0 + 16 = 17.<\/p>\n
Therefore, the decimal equivalent of the binary number 10101 is 17.<\/p>\n
Option (b), 37, is incorrect because 37 is not the decimal equivalent of the binary number 10101.<\/p>\n
Option (c), 21, is incorrect because 21 is not the decimal equivalent of the binary number 10101.<\/p>\n
Option (d), 23, is incorrect because 23 is not the decimal equivalent of the binary number 10101.<\/p>\n","protected":false},"excerpt":{"rendered":"
