Question

(x^2+5)^1/2+(x^2+5)^3/2

Answer 1

$\sqrt{ x^{2} +5} + \sqrt{ ( x^{2} +5)^{3} } = (\sqrt{ x^{2} +5})(1+ \sqrt{ ( x^{2} +5)^{2} } ) \\ =(\sqrt{ x^{2} +5})(1+ x^{2} +5 )=(\sqrt{ x^{2} +5})(x^{2}+6)$

Answer 2

(x²+5)½ + (x²+5)³/²

->(x+√5) +(x³+√125)
->(x+√5)+(x³+5√5)
->x+x³+√5+5√5
->2x³+6√5
->2(x³+3√5)
