Proceed from the given expression and keep every transformation explicit.

The last line satisfies the required domain and establishes the result.

Radical stability rises with alkyl substitution because hyperconjugation and +I donation disperse electron deficiency.

A Brønsted base forms its conjugate acid by accepting one proton.

Phosphorus uses five sp³d hybrids in trigonal-bipyramidal geometry. Each axial bond has three 90° interactions with equatorial bond pairs, whereas each equatorial bond has only two such interactions.

Metallic character increases down a group and toward the left across a period. K is farthest down-left; in period 3 Mg is left of Al; B is least metallic.

Charge is quantised in integral multiples of e.

A triangle outside \(A\) has no angle different from \(60^\circ\). Hence all three angles are \(60^\circ\), which characterises an equilateral triangle.

Total power \(=160\) W.

Apply the definition or the stated differentiation rules term by term.

Substitution into the original expression verifies the stated domain and final value.
