Concept:Rationalise the denominator by multiplying by the conjugate of the denominator, then compare with m+n6.Explanation:The conjugate of 3+22 is 3−22.Multiply numerator and denominator by this conjugate:3+2223−2×3−223−22Expand the numerator:(23−2)(3−22)=6−46−6+4=10−56Expand the denominator:(3+22)(3−22)=3−8=−5So the fraction becomes:−510−56=−2+6This must equal m+n6:m+n6=−2+16Answer:m=−2 and n=1.The correct option is B.
