、。
She can sing well and dance too.
Literal
She [topic-は] skillfully song [also-も] can-sing [and also-し], dance [also-も] can-do.
The ~し connector lists multiple qualities or facts as parallel reasons or attributes — 'she can sing, and also she can dance.' The も on both elements emphasizes inclusion: not just one talent but both. 歌える is the potential form of 歌う, and できる is the potential of する. おどり (踊り, 'dance') is written in hiragana here for a softer look.
