Jawaban : B

Pembahasan :
Bilangan berpangkat merupakan bentuk perkalian secara berulang dari suatu bilangan. Perpangkatan dapat menyederhanakan penulisan agar lebih ringkas.

Sifat bilangan berpangkat :
a^b × a^c = a^(b + c)
a = a¹
A × b^n = Ab^n

Penyelesaian :
2a² × a⁴ × a
= 2 × a² × a⁴ × a¹
= 2 × a^(2 + 4 + 1)
= 2 × a⁷
= 2a⁷

Jadi, jawaban yang tepat adalah B.
