Find the least number that must be added to 9577 to make it a perfect square number

balu736 [363]

Answer:

Step-by-step explanation:

Since it is addition to make the expression a perfect square, it would not be as direct

√9577 = 97.86214794

we round off to the nearest whole number, since we need a perfect square number

therefore it would be 98

98² = 9604, the perfect square number we'll get after adding to 9577

therefore amount needed to add= 9604-9577= 27
