Download Solution PDFGiven equation: \(17+\sqrt[2]{9}÷ \sqrt[2]{25}× 5-10=?\)
According to the question, after '+' and '−' are interchanged and '×' and '÷' are interchanged:
\(17+\sqrt[2]{9}÷ \sqrt[2]{25}× 5-10=?\) ⇒ \(17-\sqrt[2]{9}× \sqrt[2]{25}÷ 5+10=?\)
⇒ \(17-\sqrt[2]{9}× \sqrt[2]{25}÷ 5+10=?\)
⇒ 17 - 3 × 5 ÷ 5 + 10 = ?
⇒ 17 - 3 × 1 + 10 = ?
⇒ 17 + 10 - 3 = ?
⇒ 27 - 3 = ?
⇒ 24 = ?
Hence, "Option 2" is the correct answer.
