Question

Answer 1

\(A=\sqrt{50}-\sqrt{18}+\sqrt{\left(2\sqrt{2}-3\right)^2}\)

\(A=5\sqrt{2}-3\sqrt{2}+\left|2\sqrt{2}-3\right|\)

\(A=2\sqrt{2}+3-2\sqrt{2}\) ( vì \(2\sqrt{2}-3< 0\) )

\(A=3\)

Answer 2

\(A=\sqrt{50-\sqrt{18+\sqrt[]{\left(2\sqrt[]{2-3}\right)}^2}}\)

A=3

Answer 3

A = 5√2 - 3√2 + |2√2-3| 

A= 2√2 + 3 - 2√2

A = 3
