**Base ConversionsMethod 1**(Any Base Base 10)**1) Check the number for validity; each digit should be less**than the base.**e.g. 1024 is valid since each digit is less than the base.**But 1535 is invalid; 5 is not less than the base.**The person who started with this number was most likely**checking work done with method 2, since method 1 is used to check method 2.**2) Determine the positional value for each digit. Starting**with the rightmost position, give it a value of 1 (base to the zero power).**To determine the preceding positional values, multiply the**current positional value by the base e.g. 3859 3 8 5 base 9 | | | 81 9 1**3) Then multiply each digit by its positional valuee.g.**3 x 81 = 243 8 x 9 = 72 5 x 1 = 5**3 x 81 = 243 8 x 9 = 72**5 x 1 = 54) and add them together ==== 320 this is the answer in base 10**5) Finally, check the result for validity; each digit**should be less than 10. (If it is not, then you did something wrong and should start over)
