Question

Como resolver a função exponencial.
$5 ^{x2} . 5 ^{4} = 5 ^{5x}$

Answer 1

             $5^{ x^{2} } .5^4= 5^{5x} \\ \\ 5 ^{x^2+4} = 5^{5x} \\ \\ x^2+4=5x \\ \\ x^2-5x + 4 = 0 \\ \\ (x -4)(x-1)=0 \\ \\ x-4=0 \\ x1= 4 \\ \\ x-1=0 \\ x2=1$

                                                   S = { 1, 4 }
