a‾² . b‾² ＿＿＿＿ = ??? a‾¹ ＋ b‾¹ mohon bantuanx teman2, pke cara kerjax juga yah....

Hasil dari

= (a`² . b`²) : (a`¹ + b`¹)
= (1/a²b²) : (1/a + 1/b)
= (1/a²b²) : ( (b+a) / ab )
= (1 / a²b²) × (ab / b + a)
= (1 / ab) × (1 / b+a)
= 1 / (ab)(b + a)
= 1 / ab² + a²b
= 1 / (a²b + ab²)

semoga berguna +_+
