Question

What is the cubed root of 275÷7

Answer 1

Explanation:

It's an irrational number.

`\sqrt[3]{275:7}=\sqrt[3]{(275)/(7)}=\frac{\sqrt[3]{275}}{\sqrt[3]{7}}=\frac{\sqrt[3]{275}\cdot\sqrt[3]{7^2}}{\sqrt[3]{7}\cdot\sqrt[3]{7^2}}=\frac{\sqrt[3]{275\cdot49}}{\sqrt[3]{7\cdot7^2}}\\\\=\frac{\sqrt[3]{13475}}{\sqrt[3]{7^3}}=\frac{\sqrt[3]{13475}}{7}=(1)/(7)\sqrt[3]{13475}`
