Q.[tex] \sf \: f(x) = x! + x(x) \times {5}^{x}[/tex][tex] \sf \: f(5) = ...[/tex][tex] \tiny \tt \:.... Question from @FaaCha

$\bf \: f(x) = x! + x(x) \times {5}^{x}$

$\bf f(5) = 5 ! + 5(5) \times {5}^{5}$

$\bf \: f(5) = 5! + ( 25 \times ( 5 × 5 × 5 × 5 × 5 ))$

$\bf \: f(5) = 5! + ( 25 × ( 25 × 5 × 5 × 5 ))$

$\bf \: f(5) = 5! + ( 25 × ( 125 × 5 × 5 ))$

$\bf \: f(5) = 5! + ( 25 × ( 625 × 5 ))$

$\bf \: f(5) = 5! + ( 25 × 3.125)$

$\bf \: f(5) = 5! + 78.125$

$\bf \: f(5) = ( 5 × 4 × 3 × 2 × 1 ) + 78.125$

$\bf \: f(5) = ( 20 × 3 × 2 × 1 ) + 78.125$

$\bf \: f(5) = ( 60 × 2 × 1 ) + 78.125$

$\bf \: f(5) = ( 120 × 1 ) + 78.125$

$\bf \: f(5) = 120 + 78.125$

$\bf \: f(5) = 78.245$
