Question

find the difference between 7+5√2 and -3+5√2​

Answer 1

$\sf \: (7 + 5 \sqrt{2} ) - ( - 3 + 5 \sqrt{2} ) \\ \\ \sf \implies \: 7 + 5 \sqrt{2} + 3 - 5 \sqrt{2} \\ \sf \: \implies \: 7 + \cancel{5 \sqrt{2}} + 3 - \cancel{5 \sqrt{2} } \\ \\ \boxed{ \underline{\gray{ \sf{ \implies {10 \: \: ....(ans)}}}}}$

Answer 2

Answer:

$7 + 5 \sqrt{2} - ( - 3 + 5 \sqrt{2} )$
