Concept:Rationalize the denominator: multiply numerator and denominator by the conjugate (3​+2​) to simplify the expression.Explanation:First, rewrite the term 3​−2​1​. Its conjugate is 3​+2​.Multiply both numerator and denominator: (3​−2​)(3​+2​)1×(3​+2​)​=(3​)2−(2​)23​+2​​.Since (3​)2=3 and (2​)2=2, the denominator becomes 3−2=1.Thus 3​−2​1​=3​+2​.Now the whole expression is (3​+2​)+(3​+2​)=2(3​+2​).Answer:2(3​+2​) (Option D)
