Question

We all know that a binary number is a number expressed in the base-2 numeral system or binary numeral system, which uses only two symbols: typically "0" (zero) and "1" (one). For eg:- 3 written as 11, 4 as 100, 5 as 101 and so on. And if we now increase the base we get base 3 form then base 4 form and so on. Like 15 in base 3 will be written as:- 120 = 3^2(1) + 3^1(2) + 3^0(0). The method to find the base is easy: you keep on dividing the decimal number with the base and note their remainder until the number becomes 0. It’s easy to see that in the base representation none of the digits can be equal to base or exceed it keeping that in mind the addition and subtraction operation will be performed. For eg in base 3 :- 120 + 110 = 1000. In decimal it will be 15 + 12 = 27. Also if the base exceeds 10 then we will use A,B,C,D.. instead of 10,11,12…..


How many possible bases less than 100 you can use to sum 78+87.​

Answer 1

Answer:

In computer applications, where binary numbers are represented by only two symbols or digits, i.e. 0 (zero) and 1(one). The binary numbers here are expressed in the base-2 numeral system. For example, (101)2 is a binary number. Each digit in this system is said to be a bit.
