Question

Simplify the radical

Answer 1

Answer:

4 ^3√7m^2

Step-by-step explanation:

^3√64×7m^2

^3√4^3×7m^3

^3√4^3 3^√7m^2

= 4^3√7m^2

Answer 2

Answer:

$\boxed{ \tt = 4 \sqrt[3]{7m {}^{2} } }$

Step-by-step explanation:

Given,

$\sqrt[3]{448m {}^{2} }$

Solution:

• Rewrite 448 m^2:

$= \sqrt{4 {}^{3 } \times 7 \: m {}^{2} }$

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

$\tt = 4 \sqrt[3]{7m {}^{2} }$

$\rule{225pt}{2pt}$
