Question
√3601 × √(224) ÷ √102 =
? What approximate value should come in place of question mark (?) in the following questions? (You are not expected to calculate the exact value.)Solution
Here, terms of the given expressions can also be written as: √3601 × √(224) ÷ √102 = ? √3600 × √(225) ÷ √100 = ? ⇒ 60 × 15 ÷ 10 = ? ⇒ ? = 90
