Question
√ ({(5.5 × 2.3) ×
√ (728.91))} = 3(1/7) ÷ ?/28 What approximate value will come in place of question mark (?) in the given equations?Solution
√ ({(5.5 × 2.3) × √ (728.91))} = 3(1/7) ÷ ?/28 √ ({(6 × 2) × √ (729))} = 3(1/7) ÷ ?/28 √ (12 × 27) = 22/7 × 28/? => √ 324 = 88/? => 18 = 88/? => ? = 4.888 = 5
