$\sf{\longrightarrow\dfrac{{49m }^{2} }{ \sqrt{7} }}$

‎ ‎ ‎

[49 can be expanded as 7×7]

‎ ‎ ‎ ‎

$\sf{ \longrightarrow\dfrac{ {7m}^{2} \times {7m }^{2} }{ \sqrt{7} }}$

‎ ‎ ‎

[7 can also be written as √7×√7]

‎ ‎ ‎

$\sf\longrightarrow{\dfrac{ (\sqrt{7} \times \sqrt{7} \times \sqrt{7} \times \sqrt{7} ){m}^{2} }{ \sqrt{7} }}$

‎ ‎ ‎ ‎ ‎ ‎

$\sf\longrightarrow{\dfrac{ \cancel{(\sqrt{7}} \times \sqrt{7} \times \sqrt{7} \times \sqrt{7} ){m}^{2} } {\cancel{{ \sqrt{7} }}}}$

‎ ‎ ‎

$\sf{\longrightarrow (\sqrt{7} \times \sqrt{7} \times \sqrt{7}) {m}^{2} }$

‎ ‎ ‎

[√7×√7=7]

‎ ‎ ‎

$\sf{ \longrightarrow 7 \sqrt{7} {m}^{2} }$

Hence the required answer is 7√7m².
