Re: 1010 = ab Which of the following could be a + b ? [#permalink]

\(10\sqrt{10}\) = \(a\sqrt{b}\)
\(10\sqrt{10}\) can be written as:-
\(2*5\sqrt{2*5}\) which can be written as \(2\sqrt{2*5*5*5}\) or \(5\sqrt{2*5*2*2}\) or \(1\sqrt{2*5*10*10}\).
From the above we can infer a=2,b=250 or a=5,b=40 or a=1,b=1000.
Hence I,II are correct .
