Question

Simplify the radical

Answer 1

`\boxed{ \tt = 4 \sqrt[3]{7m {}^(2) } }`

Explanation:

Given,

`\sqrt[3]{448m {}^(2) }`

Solution:

• Rewrite 448 m^2:

`= \sqrt{4 {}^(3 ) * 7 \: m {}^(2) }`

• Bring terms out from the radical and write it as;

`\tt = 4 \sqrt[3]{7m {}^(2) }`

`\rule{225pt}{2pt}`

Answer 2

4 ^3√7m^2

Explanation:

^3√64×7m^2

^3√4^3×7m^3

^3√4^3 3^√7m^2

= 4^3√7m^2
