Question

valor de "a", si 483a con rayita arriba= 25°+8

Answer 1

$\overline{483a}\equiv 8 \mod 25\\ \\4830 + \overline{a}\equiv 8 \mod 25\\ \\193(25)+5+ \overline{a}\equiv 8 \mod 25\\ \\5+ \overline{a}\equiv 8 \mod 25\\ \\\overline{a}\equiv 8-5 \mod 25\\ \\\overline{a}\equiv 3 \mod 25\\\\\boxed{a=3}$
