Answer:
[tex] \sqrt[3]{7} [/tex]
Step-by-step explanation:
[tex]here \: the \: power \: of \: 7 \: is \: 3 \\ the \: cube \: represented \: by \: the \: radical \: sign \: with \: number \: 3 \\ \sqrt[3]{x} =cube \: root \: . \\ so \: we \: can \: write \: the \: given \: expression \ \: as \: \\ \: 7 \times \frac{1}{3} = \sqrt[3]{7} \\ thus \: \: the \: ans \: is \: a. \: \sqrt[3]{7} [/tex]
