Question

A fatoração completa do numero 1800 = 2a x 3b x 5c. Qual é o valor de a+b+c?

Answer 1

             Em função de seus fatores primos
                   1800/2
                     900/2
                     450/2
                     225/3
                       75/3
                       25/5
                         5/5
                         1             1800 = 2^3x3^2x5^2

                                        1800 = 2.(2^2)x3x(3)x5x(5)
                                                     a = 4
                                                     b = 3
                                                     c = 5
                                                                    a + b + c = 4 + 3 + 5 = 12
