Answer

$5x^4+5x^2+x+5$

Work Step by Step

Removing the grouping symbols and then combining like terms, the given expression, $ \left( x^4+\dfrac{2}{3}x+5 \right)+\left( 4x^4+5x^2+\dfrac{1}{3}x \right) ,$ simplifies to \begin{array}{l} x^4+\dfrac{2}{3}x+5+4x^4+5x^2+\dfrac{1}{3}x \\\\= (x^4+4x^4)+5x^2+\left( \dfrac{2}{3}x+\dfrac{1}{3}x \right)+5 \\\\= 5x^4+5x^2+x+5 .\end{array}
