\(3*( \frac{5}{4n} +1,8) = ?\)
\(3*( \frac{5}{\diagup\!\!\!\!\!4n}+ \frac{7,2n}{\diagup\!\!\!\!\!4n} ) =\)
\(3*(5+7,2n) =\)
\(15 + 21,6n =\)
\(21,6n = - 15\)
\(n = \frac{-15}{21,6}\)
\(n \approx 0.69\)
Determine the product of \(3*( \frac{5}{4n} +1,8) = ?\)
\(3*( \frac{5}{4*(0,69)} +1,8)\)
\(3*( \frac{5}{2,76} +1,8) =\)
\(3*( \approx1,8 +1,8) =\)
\(3*( 3,6) = \boxed{10,8}\)
Answer:
\(\boxed{10,8}\)
