519 : 517 + 3: 7
= 52 + 3/7 = 25\(\frac{3}{7}\) = \(\frac{178}{7}\)
519 : 517 + 3 : 7
= 52 + 3 : 7
= 25 + \(\frac{3}{7}\)
= \(25\frac{3}{7}\)
= \(\frac{187}{7}\)
\(5^{19}:5^{17}+3:7\)
\(=5^2+3:7\)
\(=25+3:7\)
\(=25\frac{3}{7}\)
\(=\frac{178}{7}\)
519:517+3:7
=52+3:7
=25+\(\frac{3}{7}\)
=25\(\frac{3}{7}\)
=\(\frac{178}{7}\)
