Answer 2

5+23=a+b3

5+23=a+b3Since rationalization of c+da+b=c+da+b×c−dc−d

5+23=a+b3Since rationalization of c+da+b=c+da+b×c−dc−dTaking L.H.S.

5+23=a+b3Since rationalization of c+da+b=c+da+b×c−dc−dTaking L.H.S.By rationalization,

5+23=a+b3Since rationalization of c+da+b=c+da+b×c−dc−dTaking L.H.S.By rationalization,7+435+23 = 7+435+23× 7−437−43

5+23=a+b3Since rationalization of c+da+b=c+da+b×c−dc−dTaking L.H.S.By rationalization,7+435+23 = 7+435+23× 7−437−43Since,   {(a+b)(a−b)=a2−b2}

5+23=a+b3Since rationalization of c+da+b=c+da+b×c−dc−dTaking L.H.S.By rationalization,7+435+23 = 7+435+23× 7−437−43Since,   {(a+b)(a−b)=a2−b2}            = [(7)2−(43
