Question

estimate sq root of 60​

Answer 1

Step-by-step explanation:

Take two perfect square numbers which are just smaller than 60 and just greater than 60.

√49 = 7 < √60 and √64 = 8 > √60

7 < √60 < 8

Multiply the inequality by 10.

70 < 10 √60 < 80

√4900 < √6000 <√6400

Move more closer to the inequality

√5929 < √6000 < √6084

77 < 10√60 < 78

Divide both sides by 10.

7.7 < √60 < 7.8

Take the average of both lower and upper limits

√60 ≈ (7.7 +7.8)/ 2

√60 ≈ 7.75
