Question

Ruestion 5/9
all know that a binary number is a number expressed in the base-2 numeral system or binary numeral
tem, which uses only two symbols typically "O" (zero) and "1" (one). For eg - 3 written as 11,4 as 100, 5 as
1 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
vill 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
e decimal number with the base and note their remainder until the number becomes 0. It's easy to see that in
e base representation none of the digits can be equal to base or exceed it keeping that in mind the addition
nd 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 ABCD instead of 10.11.12
How many possible bases less than 100 you can use to sum 78+87
