The same rule was used by some Arabian scholars² in the 14th century A. D. to approximate the value of √10. Bhāskara II³ (1150 A. D.) gave also methods of extracting the square root of surd quantities like a+√b, a+√b+√c+√d where a, b, c, d are rational. He considered also the problem of the type √(10+√24+√40+√60)=√2+√5+√3; and many others. Bhāskara II, Nārāyaṇa and others perhaps, also knew to calculate the approximate values of the surd quantities like √N by the method of continued fraction (vide chapter on Algebra).
